Abstract:

Regularities of kinetics of photoinitiated copolymerization till high conversions in the systems of monofunctional methacrylate comonomers (hydroxyethyl methacrylate (HEMA), glycidyl methacrylate (GMA)) have been investigated by laser interferometry in a wide range of experimental factors (molar ratio of comonomers, photoinitiator concentration, intensity of UV-irradiation). Kinetic model of photoinitiated copolymerization of methacrylates till high conversions has been proposed on the basis of microheterogeneity conception of the polymerization process.

Abstract:

More environmentally friendly polymeric materials for use in corrosive conditions were obtained in the process of UV polymerization of terpene methacrylate monomers: geranyl methacrylate and citronellyl methacrylate and the commercially available monomer methyl methacrylate. Selected properties (solvent resistance, chemical resistance, glass transition temperature, thermal stability, and decomposition course during heating) were evaluated. It was found that the properties of the materials directly depended on the monomer percentage and the conditioning temperatures used. An increase in the ger

Quantitative structure-property relationship (QSPR) models are developed to predict monomer reactivity ratios (log r12) in radical copolymerization with monomers M1 (styrene, methyl methacrylate and acrylonitrile) and M2 (vinyl monomers).

Stepwise multiple linear regression analysis and artificial neural network (ANN) were used to generate Model S (monomer 1: styrene), Model MM (monomer 1: methyl methacrylate) and Model A (monomer 1: acrylonitrile).

Abstract:

This work on organic dental composites was undertaken to determine the role of residual reactive methacrylate functions at the end of the photopolymerization cycle, and to investigate the fate of the residual monomers and oligomers in organic (ethanol) and aqueous (water and artificial saliva) media. The results show that all the methacrylate monomers present in dentine migrate into ethanol (about 1% (w/w)). In aqueous media on the other hand, only the most hydrophilic monomer (UDMA) migrates (0.05% (w/w)) into water and 0.03% into artificial saliva (pH = 9). This desorption in the three media

The results for methyl acrylate suggest that the copolymerization of this monomer with methyl methacrylate is adequately described by a terminal mechanism. Those for styrene show that the presence of a penultimate styrene or methyl methacrylate unit in a poly(methyl methacrylate ) radical leads to a slightly greater preference for this r

The polymerization mechanism was discussed on the basis of the optical emission spectroscopy (OES) of the plasma.

One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible.

The applications of polymers based on itaconic di-esters depend largely on their thermal stability.

The core-shell polyurethane-acrylate(PUA) emulsion containing fluorine and silicon in the core was synthesized by “one-pot” emulsion polymerization in the presence of castor oil-based polyurethane without traditional emulsifier, using methyl methacrylate (MMA), butyl acrylate (BA) as the main monomers, dodecafluoroheptyl methacrylate (G04), γ-methacryloxy propyl trimethoxyl silane (KH-570) as the functional monomers. The structure and properties of the fluorinated-silicated PUA and their films were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectrum (FT

Abstract:

Polymer dispersed liquid crystal (PDLC) films are fabricated with various compositions of E7 liquid crystal (LC), 2-Hydroxy ethyl methacrylate (HEMA), Methyl methacrylate (MMA), n-butyl methacrylate (nBMA), Ethyl methacrylate (EMA), Tetraethylene glycol diacrylate (TEGDA), and Benzoin. The results show that the refractive index of the PDLC films is insensitive to the monomer side groups. The effects of different monomers addition on the microstructure, the corresponding polymer matrix motion and electro-optical properties of the PDLC samples are examined using Dynamic Mechanical Analyzers (DMA

Abstract:

A resin monomer-soluble polyrotaxane (PRX) crosslinker with cleavable end groups was synthesized to develop degradable photosetting composite resins. The PRX containing 50 α-cyclodextrins (α-CDs) with disulfide end groups was initially modified with n-butylamine to obtain a resin monomer-soluble PRX. The PRX containing 13 n-butyl groups per α-CD molecule was completely soluble in conventional resin monomers such as 2-hydroxyethyl methacrylate (HEMA) and urethane dimethacrylate (UDMA). The synthesized n-butyl-containing PRX was further modified with 2-aminoethyl methacrylate to provide crosslin

Abstract:

Polymers are typically immiscible with one another, that is phase separated, in the absence of specific favorable intermolecular interactions, because the combinatorial entropy of mixing is small. Copolymers, polymer molecules containing more than one type of monomer unit, are frequently used to induce miscibility in homopolymer mixtures. Extensive work has previously established the importance of the copolymer composition, though the sequence of monomers within the copolymer has received less attention. Copolymers with random and with alternating sequences of monomers have been synthesized an

Abstract:

A kind of nanocomposite polymer based on poly(acrylonitrile-methyl methacrylate) [P(AN-MMA)] copolymer was prepared by in situ polymerization of monomers on the surface of TiO2 nanoparticles, which come from the hydrolysis of Ti(OC4H9)4. Analysis of Fourier transform-infrared (FT-IR) spectra indicated that the acrylonitrile (AN) monomers copolymerized with the methyl methacrylate (MMA) monomers by breaking their own double bonds. The dependence of ionic conductivity on temperature for the resulting nanocomposite polymer electrolyte (NCPE) followed the Arrhenius equation. The ionic conductivity

Abstract:

New functional monomers bearing a methacrylate, a bisphosphonate function and, for most, an internal carboxylate group, were prepared for incorporation into copolymers with adhesive or anticorrosive properties. Methanolysis of some trimethylsilyl bisphosphonate esters not only deprotects the desired bisphosphonate function but also regioselectively cleaves the alkyl ester function without affecting the methacrylate ester.

Abstract:

Diazepam is a benzodiazepine that has the potency to be misused because it is effective, easily obtained, and inexpensive. The misuse of diazepam is to replace illegal drugs and be a sedative. Separation of diazepam is needed to detect possible drug abuse and to monitor drug levels in blood to ensure the effectiveness of the drug. This study was conducted to obtain a molecularly imprinted solid-phase extraction (MI-SPE) sorbent to separate diazepam from serum samples. This work started at the synthesis stage with the bulk polymerization method, using methyl methacrylate and acrylamide as funct

Polymerization proceeds readily through a thermal free radical initiation. The intensity exponents for the monomer and initiator are only slightly over 1 and approximately 0.5, respectively. This is in accordance with the results typically observed for an ideal free radical polymerizatio

Monomers are released from dental resin materials, and thus cause adverse biological effects in mammalian cells. Cytotoxicity and genotoxicity of some of these methacrylates have been identified in a vast number of investigations during the last decade. It has been well-established that the co-monomer triethylene glycol dimethacrylate (TEGDMA) causes gene mutations in vitro. The formation of micronuclei is indicative of chromosomal damage and the induction of DNA strand breaks detected with monomers like TEGDMA and 2-hydroxyethyl methacrylate (HEMA). As a consequence of DNA damage, the mammali
