Abstract:

The results of experimental studies of the composition of individual substances migrating from medical rubber plugs produced both in and abroad based on technical bromobutyl rubber are presented. The quantitative content of volatile organic compounds related to species impurities of gasoline was determined by gas chromatography from a standard glass bottle sealed with a sterile stopper based on bromobutyl rubber. The method of atomic emission spectroscopy was used to determine (indirect) the presence of organometallic, organosulfur and metal-inorganic compounds that did not pass through chroma

Abstract:

Abstract An analysis of the 1H and 13C NMR spectra of the chlorobutyl and bromobutyl rubbers was performed. Peaks were assigned based on evidence from broad-band decoupled, off-resonance decoupled, selectively decoupled and J-modulated spectra, the known characterization of butyl rubber and halogenation studies on model compounds. The assignment of the minor peaks indicated that the exomethylene-type structure is predominant in both halogenated rubbers. They also contain some nonhalogenated isoprenyl units. Bromobutyl rubber also contains some α-bromomethyl-type structures resulting from rearr

Abstract An investigation of the effects of polystyrene—polyisobutylene linear triblock and three-arm star block thermoplastic elastomers on the processability and properties of butyl and bromobutyl rubbers was undertaken. All properties improved, with the exception of bromobutyl adhesion, which remained acceptable. The green strength of raw polymer blends improved by 30–80% and 5–20% improvement was seen on the carbon black compounds. Die swell was reduced by as much as 60% for compounds containing a triarm-star block. Tear strength doubled and air permeability decreased (by about) 20–40%. Fa

ABSTRACT Optimizing the maintenance cycles of rubber-lined components is of great importance. Especially for the industry sectors operating under demanding conditions, challenges in the lifetime evaluation of rubber linings may cause apparent premature failures. Thus, understanding the effect of environmental factors on the performance and durability of rubber linings, as well as on the weakest links of the structure in certain environments, is essential.

Abstract:

Abstract The 1H-NMR results show that the majority of the isoprene units of butyl rubber are incorporated in 1,4 addition. Approximately 6% of the isoprene units undergo 1,2 enchainment. Based on our study of blends of polyisoprene with polyisobutylene, 1H-NMR provides an excellent method for determining isoprene unsaturation in butyl rubber. Furthermore, based on 1H-NMR measurement, FTIR procedures have been developed to quantify the isoprene content of butyl polymers and the concentrations of the three major bromobutyl isomers.

ABSTRACT The impact of thermo-oxidation on the permeation process in a series of BIIR or bromobutyl compounds has been investigated. Methyl salicylate (MS) was used as the simulating chemical agent, and the permeation rate was measured gravimetrically using vapometers. Heat aged samples at 120 °C increased in stiffness with an accompanying decline in ultimate properties and network chain density. A reduction in permeability was found, driven primarily by the reduced solubility of MS in the thermo-oxidized BIIR matrix. The formation of a secondary oxidized chain network has been proposed to exp

Abstract Vulcanization of isobutylene/isoprene copolymer (butyl rubber) using sulfur and organic accelerators is facilitated by the presence of the carbon-carbon double bond in the copolymer isoprenyl unit. The low number of unsaturated monomer units, usually in the order of 2%, has traditionally necessitated use of ultra-fast accelerators such as tetramethyl thiuram disulfide (TMTD) or zinc dimethyldithiocarbamate (ZMDC). Use of such accelerators can result in formation of nitrosamines which may be undesirable. There are a number of alternatives to thiuram and dithiocarbamate cure systems suc

Abstract 1. In halobutyl elastomers, zinc oxide interacts synergistically with aromatic amine antioxidants such as APDA 86, DPPD, or DNPD, to produce fast, tight cures. 2. In the case of DNPD, compound storage stability appears to be satisfactory, and the resistance to scorch at processing temperatures is ample. 3. The cure behavior of these systems, particularly in bromobutyl, is exceptionally favorable: a rapid rise to a remarkably flat plateau. 4. The vulcanizates exhibit excellent thermal stability (compression set) and excellent ozone resistance. Measurable elastic properties are retained

Abstract:

Abstract The performance of butyl, chlorobutyl, bromobutyl, and brominated isobutylene-co-para-methylstyrene (BIMS) rubbers were evaluated versus a solution-polymerized styrene-butadiene rubber with 20% bound styrene in model winter tire tread formulations containing natural rubber and butadiene rubber. Isobutylene-based elastomer performance was compared in carbon black-filled and silane-coupled silica-filled systems. Based on laboratory dynamic properties predictive of wet and winter traction, and on DIN abrasion index values, BIMS is the elastomer of choice affording increased tangent delta

Abstract:

The effectiveness of separate and combined incorporation of two natural, inexpensive, and nontoxic filler materials, kaolin and talc, at their various proportions in a bromobutyl rubber (BIIR) compound for a medical syringe plunger was investigated. The dispersion of kaolin was finer and more homogeneous than talc in BIIR. The curing was also enhanced in the presence of kaolin than talc. The difference in dispersion as well as reinforcing effects of the different fillers were reflected in the dynamic mechanical properties of the compounds. Tensile properties of the compounds were not significa

Abstract:

1-(2-Bromobenzyl)-2-alkanesulfonylpyrroles (1c, 1d) and 1-(4-bromobutyl)-2-methylsulfonfylpyrrols (8) undergo oxidative radical cyclization with partial or complete reductive desulfonylation to the pyrrolizidine derivatives 5 and 9 by an AIBN initiated reaction with tri-n-butyltin hydride. These cyclizations are suggested to proceed via a pseudo SRN1 process involving radical addition to the α position of the pyrrole nucleus not bearing the sulfonyl group. Reductive removal of the alkylsulfonyl moiety is proposed to occur in a second process after completion of the oxidative radical cyclizatio
