摘要
A hydrogenated copolymer rubber which is a hydrogenation product of a random copolymer rubber consisting of:PP(A) 30-70 mole % of a unit derived from at least one monomer selected from the group consisting of alkyl acrylates and alkoxy-substituted alkyl acrylates, PP(B) 20-70 mole % of a unit derived from at least one conjugated diene, andPP(C) 0-10 mole % of a unit derived from at least one other ethylenically unsaturated compound copolymerizable with the components (A) and (B) [(A)+(B)+(C)=100 mole %] wherein at least 90% of the double bonds of the conjugated diene unit is hydrogenated; a crosslinkable rubber composition comprising said hydrogenated copolymer rubber and a crosslinking agent; and a thermoplastic polymer comprising said hydrogenated copolymer rubber and a thermoplastic resin. These rubbers and compositions are superior in low- temperature resistance, heat resistance, ozone resistance, mechanical strengths, compression set, impact resilience and oil resistance.
