Abstract:

Poly(styrene-divinylbenzene) microspheres were prepared by seed swelling polymerization in the presence of tung oil methyl esters. First, the core monodisperse polystyrene microspheres were prepared by a dispersion polymerization method. Using polystyrene microspheres as seed, tung oil methyl esters as a functional monomer, divinylbenzene as crosslinker, poly(styrene-divinylbenzene) microspheres were prepared by seed swelling polymerization. Then they were characterized by using FT-IR spectroscopy, TG/DSC and optical microscopy. Results showed that the tung oil methyl esters did participate in the copolymerization of styrene and divinylbenzene.

Abstract:

Hollow polystyrene nanocapsules with sizes of ~100 nm have been prepared via a miniemulsion polymerization process by applying the encapsulation of a nonsolvent (i.e., isooctane). Divinylbenzene has been added to styrene as a cross-linking comonomer in order to improve a structural stability of the hollow polymer capsules. Morphology variation of nanocapsules with concentrations of divinylbenzene and also isooctane has been studied using transmission electron microscopy analysis. Kinetic study on the miniemulsion polymerization of styrene in the presence of divinylbenzene and isooctane has been carried out using fractional conversion data determined by the gravimetric analysis.

Abstract:

Four vinyl polymer gels (VPGs) were synthesized by free radical polymerization of divinylbenzene, ethane-1,2-diyl dimethacrylate, and copolymerization of divinylbenzene with styrene, and ethane-1,2-diyl dimethacrylate with methyl methacrylate, as supports for palladium nanoparticles. VPGs obtained from divinylbenzene and from divinylbenzene with styrene had spherical shapes while those obtained from ethane-1,2-diyl dimethacrylate and from ethane-1,2-diyl dimethacrylate with methyl methacrylate did not have any specific shapes. Pd(OAc)2 was impregnated onto VPGs and reduced to form Pd0 nanoparticles within VPGs. The structures of Pd0-loaded VPGs were analyzed by XRD, TEM, and nitrogen gas adsorption. Pd0-loaded VPGs had nanocrystals of Pd0 within and on the surface of the polymeric supports. Pd0/VPGs efficiently catalyzed the oxidation/disproportionation of benzyl alcohol into benzaldehyde/toluene, where activity and selectivity between benzaldehyde and toluene varied, depending on the structure of VPG and the weight percentage loading of Pd0. The catalysts were stable and Pd leaching to liquid phase did not occur. The catalysts were separated and reused for five times without any significant decrease in the catalytic activity.

Abstract:

Methacrylic acid copolymers crosslinked with 0.25-16 % divinylbenzene were synthesized by free radical polymerization using benzoyl peroxide as an initiator. The products were washed, dried and passed through a 80-mesh sieve prior to determining their infrared spectra, swelling capacity in water and disintegrant efficacy for microcrystalline cellulose (MCC) placebo tablet. The crosslinked methacrylic acid and divinylbenzene copolymers were successfully prepared as indicated by IR spectra, yielding around 50-80 %. The sieved particles of copolymers were white to faint yellow. In contact with water, they hydrated and swelled, where their swelling capacity was lowered with increasing the level of crosslink (divinylbenzene) in the copolymer structure. The copolymer with 0.25 % crosslink caused the MCC tablet to disintegrate fastest (1.2 min), corresponding to its highest swelling capacity. The disintegration efficacy increased with an increase in copolymer concentrations, but decreased with an increase in compression forces.

Abstract:

An automated headspace solid-phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) method was developed to monitor the occurrence of selected haloacetonitriles (HANs), haloketones (HKs), and chloropicrin (CP) in drinking water supplies. The method was rapid with analysis time of 30 min, including extraction and chromatographic run. Chemical ionization (CI) was used to increase the sensitivity of the method for the HKs. SPME fibers with seven different coatings including commercial polyacrylate (PA), carbowax/divinylbenzene (CW/DVB), polydimethylsiloxane (PDMS), polydimethylsiloxane/divinylbenzene (PDMS/DVB), carboxen/polydimethylsiloxane (CAR/PDMS), divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS), and a novel custom-made polydimethylsiloxane/divinylbenzene-N-vinylpyrrolidone (PDMS/DVB-NVP) were evaluated. The DVB/CAR/PDMS fiber was found more suitable for the range of the analytes and the novel PDMS/DVB-NVP fiber more efficient for the brominated acetonitriles under the experimental conditions. Method detection limits (MDLs) for the chlorinated acetonitriles and CP varied between 2 and 40 ng/L and for the brominated acetonitriles and HKs between 100 and 180 ng/L. Relative standard deviations (RSD %) of measurements were 4–7%. The method was applied in parallel with a liquid–liquid extraction gas chromatography electron capture detection (LLE-GC-ECD) method (EPA Method 551.1) to the analysis of drinking water samples from eight Canadian water treatment and distribution systems. The results generated by the two methods showed good agreement.

Abstract:

Porous poly(para-divinylbenzene) and poly(meta-divinylbenzene) particles were synthesized from para-divinylbenzene and meta-divinylbenzene monomers with toluene and 2-ethylhexanoic acid as porogens. The residual vinyl groups in the particles were thereafter reacted with lauroyl chloride by using the Friedel–Crafts reaction. The conversion of vinyl groups was followed by analyzing polymer particles taken from the reaction mixture at different time intervals. Infrared spectroscopy in both the mid- and near-infrared region was used as the analytical technique. The intensity changes in the overtone absorption at 1628 nm due to the vinyl bonds were used as the basis for the quantification of the reaction. Spectra of the particles in the mid-IR region provide understanding of the changes taking place in the polymer matrix during the acylation reaction. The results indicated that the reaction took place at a faster rate in the polymer particles synthesized from para-DVB monomer compared with the poly(meta-DVB) particles. The polymer particles synthesized with toluene as porogen react faster than the polymer particles prepared with 2-ethylhexanoic acid as the porogen. The analysis also indicated that the acylation takes place at the early stages of the reaction and the product formed transforms into more stable products at the latter stages. On the basis of the infrared analysis, mechanisms for the formation of the different products are proposed.

Abstract:

Magnetite nanoparticles (MNPs) coated with poly (divinylbenzene-co-glycidyl methacrylate) particles (mPDGs) are prepared by co-polymerization of 1,4-divinylbenzene and glycidyl methacrylate monomers via batch emulsion polymerization. The Fe3O4nanoparticles modified by oleic acid are obtained by chemical precipitation. The chemical composition, morphology, magnetic content, magnetic properties and particle size of the composite particles are investigated using transmission electron microscopy, thermogravimetric analysis, vibrating sample magnetometer, and dynamic light scattering, respectively. The results show that the magnetic nanoparticles have been coated by 1,4-divinylbenzene and glycidyl methacrylate, with the high saturation magnetization being 33.66 emu/g. The mean size of the mPDGs with good dispersion is about 200 nm. Subsequently, the polymer shell with reactive epoxy group is expected to be useful for chemical grafting of any biomolecule containing reactive functional groups (-NH2, -OH, -COOH, etc) or can be chemically modified to desired functional groups. These magnetic nanospheres with multifunctional groups have potential application in biomedical applications.

Abstract:

Amination of vinylbenzyl chloride-divinylbenzene (VBC-DVB) copolymers is an effective method for preparation of ion-exchange resins. Conventionally, the starting polymer is produced by chloromethylation of a styrene-divinylbenzene copolymer that utilizes chloromethyl methyl ether, a known carcinogen. An alterative approach is to copolymerize vinylbenzyl chloride with divinylbenzene to generate the necessary VBC-DVB. This method provides precise control over the density of the ion-exchange groups. The regiochemistry of the vinylbenzyl chloride methods was realized using solvent-ion exchange groups. In this investigation, an improved solvent system was found for the preparation of anion exchange resins by the vinylbenzyl chloride route. The effectiveness of amination of the intermediate VBC-DVB polymers with a variety of trimethylamine reagents was investigated, and ethanolic trimethylamine produced the highest degree of amination. These resulting ion-exchange polymers were characterized by a variety of techniques such as analytical titrations, nitrogen analysis, Fourier transform infrared spectroscopy and thermal gravimetric analysis. Testing of these copolymers for breakthrough was performed. The results indicate that these anion exchangers have a meaningful increase in thermal stability over commercial anionic exchange beads.

Abstract:

The volatile components of Murraya koenigii fresh leaves, collected from Surat Thani province, Thailand were studied by using headspace (HS) solid-phase microextraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The four fibers employed to extract the volatiles were polydimethylsiloxane (PDMS), polydimethylsiloxane-divinylbenzene (PDMS-DVB), carboxane-polydimethylsiloxane (CAR-PDMS) and polydimethylsiloxane-divinylbenzene-carboxane (PDMS-DVB-CAR). The volatile constituents of M. koenigii fresh leaves were also extracted by hydrodistillation and analyzed by GC-MS. Fifty-one compounds were identified by these fibers. Five major compounds, γ–terpinene, β-caryophyllene, β-phellandrene, α-selinene and α-pinene, were detected in all fibers. The PDMS-DVB-CAR fiber was considered as the best for trapping key volatiles of M. koenigii fresh leaves.

Abstract:

The solid-phase microextraction (SPME) technique was applied and optimized for collection of volatile compounds emitted from oestrous urine of mares Equs cabalus L. (Perissodactyla, Equidae) for GC-MS analyses. Variables such as type of SPME fi bre, collection time of volatiles, and addition of salt were optimized to improve the sampling effi ciency in two aspects: extent and selectivity of absorption/adsorption of urine volatiles onto SPME fi bres. The data revealed that the number of volatiles and the total amount represented as quantitative peak areas of the compounds trapped on fi bres coated either with polydimethylsiloxane- divinylbenzene or with divinylbenzene-carboxen-polydimethylsiloxane were signifi cantly higher compared to those coated with polydimethylsiloxane, polyacrylate, and carbowax-divinylbenzene. The polydimethylsiloxane-divinylbenzene-type of fi bre coating was chosen for optimization of sampling time and effect of salt addition. Sampling periods lasted for 15, 30, 60, 120, and 240 min. The optimal collection time of volatiles from urine maintained at about 36 °C was 60 min, as the number of compounds detected with amounts suffi cient for quantifi cation did not differ signifi cantly from those trapped during longer collection periods. No signifi cant increase in total amount of volatiles trapped was registered after 120 min of sampling. Addition of 0.3 g NaCl to the 2-ml of samples shortened the collection period from 60 to 15 min during which almost all compounds were trapped. Addition of salt has a signifi cant effect at all sampling periods taking into consideration the total amounts of volatiles trapped. The total intensities increased about 8, 5, 3, 3, and 2 times at collection periods of 15, 30, 60, 120, and 240 min, respectively, when compare with the ones obtained from the urine samples with no salt addition. In oestrous mare’s urine, 139 ± 4 (average number ± standard deviation) volatile compounds suitable for quantitative analyses were detected compared to 45 compounds collected by the gas-tight syringe method.
