ABSTRACT:
Vulcanized rubber parts suitable to dampen vibrations generated by mechanical devices are disclosed. The parts are based on a cured composition comprising one or a mixture of a diolefin polymers, e.g., natural rubber, a halogenated copolymer of a C.sub.4 to C.sub.7 isomonoolefin, e.g., isobutylene, and a para-alkylstyrene, filler and a curing system. The vulcanized parts exhibit improved aging and high temperature resistance and reduced deterioration of dynamic properties after long term exposure to high temperatures.
