POLYOLEFIN GRAFT COPOLYMER PRODUCED WITH COORDINATION POLYMERIZATION CATALYST BASED ON COMPLEX OF TRANSITION METAL APPEARING IN LATER PERIOD AND PROCESS FOR PRODUCING THE SAME

摘要

A novel polyolefin graft copolymer which is obtained by graft−copolymerizing an olefinic monomer with a (meth)acrylic macromonomer or isobutylene macromonomer in the presence of a coordination polymerization catalyst based on a complex of a transition metal appearing in a later period; a novel composition; and a process for producing the copolymer.
