POLYOLEFIN RESIN COMPOSITION

摘要

This is a new polyolefin resin which enhances adhearance of the coating layer without pretreatment. This resin is composed of A) crystalline polyolefin resin 30-90 wt.%; B) ethylene-α-olefin copolymer rubber grafted with α,β-unsat. carboxylic acid and its deriv. 5-60 wt.%; C) polypropylene resin 1-30 wt.% not reacting with funtional group of (B); and D)ethylene-α-olefin copolymer 1-40 wt.%. This composition does not need pretreatment or primers when coating with urethane paints and it maintains mechanical properties.
