POLYISOBUTYLENE/POLYOLEFIN COPOLYMER AND PROCESS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an efficient method for synthesizing a polyisobutylene-graft-polyolefin and/or a polyisobutylene-block-polyolefin, a composition comprising the copolymer or copolymers, and a method for manufacturing the copolymers.;SOLUTION: The polyisobutylene-polyolefin copolymer is manufactured by performing a cationic polymerization in the presence of a polyolefin macromonomer with a vinylidene terminal to form a polymeric segment mainly composed of isobutylene.;COPYRIGHT: (C)2004,JPO
