摘要： An ethylene-.alpha.-olefin-non-conjugated diene copolymer rubber composition which comprises two kinds of ethylene-.alpha.-olefin-non-conjugated diene copolymers, �the copolymers (A) and (B)!, copolymer (A) containing ethylidenenorbornene and either dicyclopentadiene or .alpha.,.omega.-diene having 8 to 20 carbon atoms in the main chain as the non-conjugated dienes, copolymer (B) containing ethylidenenorbornene as the non-conjugated diene, the weight ratio of the copolymer (A) to the copolymer (B) being 30/70 to 70/30, wherein the copolymer (A) has a relatively low molecular weight, a specific ethylene/.alpha.-olefin weight ratio and a specific non-conjugated diene content and the copolymer (B) has a relatively high molecular weight and a specific ethylene/.alpha.-olefin weight ratio. Said copolymer rubber composition, when highly foamed, shows no reduction particularly in low tensile stress, and is excellent in shape-retention during cross-linking and foaming, and in compression set and processibility.

摘要： A rubber composition comprising (a) a low molecular weight copolymer rubber which is an ethylene/&agr;-olefin/non-conjugated diene copolymer rubber having a limiting viscosity [&eegr;] of 0.4-1.6 dl/g measured in decalin at 135° C., and an ethylene content of 40-60 wt % and (b) a high molecular weight copolymer rubber which is an ethylene/&agr;-olefin/non-conjugated diene copolymer rubber having a Mooney viscosity (ML1+4,100° C.) of 60-150, an ethylene content of 60-80 wt %, and an iodine number of 5-35, wherein the difference between the iodine number of the low molecular weight copolymer rubber (a) and the iodine number of the high molecular weight copolymer rubber (b) is 5 or less and the ratio by weight of the low molecular weight copolymer rubber (a) and the high molecular weight copolymer rubber (b) is 50/50 to 80/20, the rubber composition having a Mooney viscosity (ML1+4,100° C.) of 20-50. The rubber composition exhibits superior roll processability and extrusion processability, excellent surface appearance and adhesiveness, can be processed easily, and produces vulcanized rubber exhibiting excellent mechanical characteristics and good low and high temperature properties.
