Olefin based random copolymer

Abstract

Abstract PURPOSE:To obtain the novel title copolymer consisting of a specific alpha-olefin and alpha,omega-diene and having specified number average molecular weight, diene component content and content insoluble in boiled toluene and having excellent roll operability low hardness and low impact resilience. CONSTITUTION:The aimed copolymer obtained by copolymerizing (A) 4-20C alpha-olefin (preferably hexene-1) with (B) 9-20C alpha,omega-diene (preferably 1,9-decadiene) and having 50,000-5,000,000 number average molecular weight expressed in terms of polystyrene, 1-5mol% content of the component B and 1-3wt.% content insoluble in boiled toluene. The above-mentioned copolymer is e.g., obtained by carrying out polymerization using a Ziegler-Natta catalyst obtained by combining a carried titanium catalyst containing Ti and Mg as an essential ingredients with an organoalminium compound. Furthermore, polymerization temperature is preferably 20-60 deg.C and polymerization pressure is normally preferably 0-20 atomic pressure.
