摘要： A halogenated butyl polymer having improved properties, the butyl polymer derived from a monomer mixture comprising a C4 to C8 monoolefin monomer, a C4 to C14 multiolefin monomer and a styrenic monomer with a catalyst system to produce the butyl polymer. The improved properties include faster cure, higher maximum torque, higher delta torque, relatively stable modulus over time, improved hot air aging properties and improved aged flexure properties. These improved properties are believed to result from direct interaction between the styrenic moieties in the polymer backbone with a crosslinking agent added to vulcanize the halogenated butyl rubber.

摘要： This invention relates to a novel class of polymeric resins which have a softening point ranging from about 50null C. to about 220null C. and a molecular weight ranging from about 500 to about 42,000. The resins consist essentially of the polymers which result from the polymerization reaction between dicyclopentadiene and limonene. The polymeric resins are particularly useful in improving traction of the rubber when used in tire treads.
