Abstract
PURPOSE: To obtain industrially and advantageously title rubber having high strength characteristics and transparency, by a method wherein ethylene is copolymerized with 1-butene and a polyene in the presence of a catalyst composed of an organovanadium cpd. and an organoaluminum cpd. in a specified molar ratio.
CONSTITUTION: Ethylene copolymer rubber is produced by copolymerizing ethylene, 1-butene and a polyene at a temp. of 40W100°C in the presence of a catalyst composed of (A) an organovanadium cpd. of formula I (wherein R is hydrocarbon X is halogen; 0<n≤3) and (B) an organoaluminum cpd. of formula II (wherein R' is hydrocarbon; X' is halogen; 1<m≤1.5) in a mole ratio of Al/V of not less than 5 in such a proportion as to give a mole ratio of ethylene/1-butene of 86/14W95/5 and an iodine value of 2W40.
