ABSTRACT:
A rubbery copolymer of ethylene, 1-butene and a polyene, characterized by having (A) an ethylene/1-butene mole ratio of from 86/14 to 95/5, (B) an iodine value of from 2 to 40, (C) an intrinsic viscosity [.eta.], measured in decalin at 135.degree. C., of from 0.8 to 4 dl/g, and (D) a weight average molecular weight
umber average molecular weight ratio (Mw/Mn) of less than 3; and a process for the production thereof.
