ELASTOMER WITH IMPROVED HEAT AND OIL RESISTANCE BASED ON MODIFIED CHLORINATED POLYETHYLENE

摘要

ABSTRACT OF THE DISCLOSURECOPOLYMER ELASTOMER WITH IMPROVEDHEAT AND OIL RESISTANCE BASED ONMODIFIED CHLORINATED POLYETHYLENEA chlorinated polyethylene elastomer or resin is modi-fled by graft copolymerization with acrylic ester type ofmonomeric material, having a glass transition temperatureof not greater than 6°C, in an amount sufficient to providean ester group (-COO-) content of from 25 to 40% by weight,to yield a mixed copolymerizate vulcanizable to a heat andoil resistant elastomeric state.
