摘要： Improved green strength of elastomers made from monomers selected from the class consisting of at least one conjugated diene having from 4 to 10 carbon atoms, olefins having from 2 to 14 carbon atoms along with a diene having from 4 to 6 carbon atoms, and combinations thereof, is achieved by adding an amount of a polydimethylbutadiene compound to form a blend having a glass transition temperature of from about 0.degree. C to about -100.degree. C. The polydimethylbutadiene compound may be merely the homopolymer of dimetylbutadiene, the copolymer, the terpolymer or the tetrapolymer of dimethylbutadiene in various combinations with monomers such as butadiene, isoprene, piperylene, acrylonitrile, vinylidene chloride, vinyl pyridine, methacrylic acid and vinyl substituted aromatic compounds.

摘要： The subject invention relates to comb polymers having a halobutyl rubber backbone and to techniques for synthesizing such polymers. The comb polymers of this invention can be thermoplastic elastomers. For instance, halobutyl rubbers having sidechains which are derived from vinyl aromatic monomers are thermoplastic elastomers which can be made by a technique of the subject invention. Such thermoplastic elastomers typically have a chlorobutyl rubber backbone and side chains which are comprised of polystyrene. The subject invention more specifically discloses a process for grafting a lithium terminated vinyl aromatic polymer onto a halobutyl rubber which comprises: (1) capping the lithium terminated vinyl aromatic polymer with a diene monomer to produce a lithium terminated diene capped vinyl aromatic polymer, and (2) reacting the lithium terminated diene capped vinyl aromatic polymer with the halobutyl rubber to produce a halobutyl rubber having vinyl aromatic sidechains grafted thereto.
