Cohesive strength of these adhesives can be modified by blending butyl rubber and polyisobutylene. Higher strength is obtained by using high molecular weight PIB or butyl rubber. On the other hand, blends of butyl rubber or PIB with chlorinated butyl rubber show improved cure properties. [Pg.650]

Curing systems. Four curing systems can be used for BR and chlorinated butyl rubber formulations. [Pg.652]

Chlorinated butyl rubber. Chlorination or bromination of butyl rubber overcomes the difficulty of vulcanising butyl rubber in mixtures with more highly unsaturated substances due to the preferential absorption of the sulphur by the more highly unsaturated component. Chlorohydrin Rubbers... [Pg.17]

Although two dissimilar elastomers—e.g., chlorinated butyl rubber and polybutadiene—may crosslink when in contact with one another, does bonding exist between the two interfaces Based upon thermodynamic theory as well as microscopic observations, we know that two such elastomers are not molecularly dispersed in a blend, so the diagnostic problem is one of considering two dispersed phases. [Pg.97]

More recently, the dehydrohalc enation of chlorinated butyl rubber, i. e. iso-butene-isoprene copolymer containing 1.4—1.6 wt % of chlorine, essentially in allylic positions, was performed successfully thus poljdsobutraie chains carrying randcxn groups of two conjugated double bonds were obtained. [Pg.4]

The introduction of conjugated diene functions in polyisobutene chains has been recently acconq>lished throu an indirect approach which utilizes the dehydro-haiogenation of chlorinated butyl rubber, i. e. randomly chlorinated poly(isobutene-co-isoprene), by means of basic agents ... [Pg.11]

PP was blended with 5-50 parts of chlorinated butyl rubber, CBR, in the presence of a non-peroxide curative (e.g., oxides or sulfides of Zn, Cd, Mn, Fe, or Pb) on a roll mill at 138-157 °C. The dynamic vulcanization resulted in materials useful for high tensile strength applications... [Pg.1667]

The efficiency of grafting indene from chlorinated butyl rubber was found to be enhanced by a side reaction in which indene homopolymer was grafted onto the macro-initiator. Efficiencies of 100% were obtained with this system. [Pg.14]

Chlorinated butyl rubber also contains a small amount of allylic chlorine. With diethyl aluminium chloride, cationic sites may be generated at these points on the chain leading to grafting in the presence of polymerizable monomers such as indene. ... [Pg.277]

Trathnigg and co-workers [97] have quantitated copolymers and blends using a dual concentration detector. Xu and co-workers [98] used UV absorbance and differential refractive index detectors in conjunction with SEC to study the copolymer composition of chlorinated butyl rubber/PS comb graft copolymers as a function elution volume. [Pg.11]

Vulcanization rates are higher than for normal butyl rubber because the presence of allylic halide increases the reactivity of the unsaturated sites. Brominated butyl rubber shows higher vulcanization rates than chlorinated butyl rubber. Halogenated butyl rubbers can be vulcanized with various reagents, e.g. diamines, dihydroxy aromatic compounds and zinc oxide. [Pg.72]
