Abstract

PURPOSE: To provide a rubbery ethylene copolymer having high strength characteristics and good working characteristics, obtd. by copolymerizing ethylene, butene and a specified polyene.
CONSTITUTION: There is provided ethylene-1-butene-polyene copolymer composed of ethylene, 1-butene and a polyene selected from dicyclopentadiene and 5-vinyl-2- norbornene in a mole ratio of ethylene/1-butene of 86/14W95/5 having an iodine value of 2W40, a limiting viscosity number [η] of 1.0W4.0dl/g (in decalin at 135°C), a value (Q) of weight-average MW/number-average MW of less than 3, and (F) where an ethylene-1-butene random copolymer having an ethylene content of 90mol% which shows the same weight-averange MW (by light-scattering method) has a limiting viscosity number [η]'=gη of 0.2W0.9.
