Abstract

PURPOSE: To obtain the titled copolymer useful as a rubber material, having improved heat stability, oil resistance, processing workability, curing rate, etc., by chlorinating a specific ethylenic terpolymer in an aqueous suspension by two stages.
CONSTITUTION: A powdery copolymer of ethylene-α-olefin-5-ethylidene-2-norbornene, having a molar ratio of ethylene to α-olefin of (85W95)/(15W5), an iodine value of 5W20, and a melt index of 1W30, in an aqueous suspension, is chlorinated at 50W70°C upto a chlorine content of 10W15wt%, and at 70W100°C after that, to make a chlorine content of 20W35wt%.
