Production of polyolefin copolymer
Abstract
Abstract PURPOSE:To obtain a copolymer which has excellent adhesiveness to metal and various resins and is useful as a compatibility improver in the mixing of polyolefins with various resins, by reacting a modified polyolefin with a polar polymer contg. an epoxy group. CONSTITUTION:A modified polyolefin obtd. by reacting an unsaturated carboxylic acid (anhydride) such as maleic acid (anhydride) or (meth)acrylic acid with a polyolefin such as PE, PP or an ethylene/propylene/diene terpolymer rubber is reacted with a polar polymer contg. an epoxy group such as a glycidyl methacrylate/methyl methacrylate/ethyl acrylate copolymer to obtain the titled copolymer. This copolymer has excellent adhesiveness to metal and various resins and is well compatible with various resins, because the moiety to be grafted onto polyolefins is a polymer. Therefore, the copolymer is effective as a compatibility improver in the mixing of polyolefins with various resins, and has transparency.
