COATING COMPOSITION FOR POLYOLEFIN RESIN AND PROCESS FOR PRODUCING THE SAME

摘要

A coating composition for polyolefin resins, characterized by containing a resin obtained by graft-polymerizing at least one member selected among alpha beta unsaturated carboxylic acids and acid anhydrides thereof with at least one member selected among polypropylene and propylene alpha olefin copolymers, chlorinating the graft copolymer to give an acid-modified chlorinated polyolefin, incorporating a (meth)acrylic ester having one hydroxyl group into the polyolefin through an ester bond, and then graft-polymerizing a (meth)acrylic acid monomer with the polyolefin; and a process for producing the composition.
