ABSTRACT:
By blending 5-40 parts by weight of a polyisoprene having an intrinsic viscosity [n] of 0.2-1.5 dl/g as measured in toluene at 30.degree. C. and a total 1,2- and 3,4-configuration content of 30% or less in its micro-structure into 100 parts by weight of an ethylene-propylene rubber, the adhesive property of the ethylene-propylene rubber to fibers can be improved while maintaining the heat resistance, weather resistance, ozone resistance, low temperature properties, electrical insulating property and chemical resistance which are all characteristic of ethylene-propylene rubber.
