Abstract
Abstract An epoxy-modified polyolefin wax, which consists of a low-molecular-weight polyolefin grafted, copolymerized and modified with an epoxy group-containing, ethylenically unsaturated compound and has a number average molecular weight of from 600 to 10,000 and an epoxy equivalent of from 200 to 100,000, is disclosed. This epoxy-modified polyolefin wax is very valuable as a modifier for improving brittleness or adhesion (adhesiveness) in various resins, especially thermosetting resins.
