ABSTRACT:
A modified polyolefin comprising: (A) 100 parts by weight of a polyolefin; (B) 0.01 to 20 parts by weight of a monomer mixture consisting of: (b-1) 5 to 50% by mole of glycidyl acrylate, glycidyl methacrylate or an unsaturated glycidyl compound represented by general formula (I) below ##STR1## wherein R is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; Ar is an aromatic hydrocarbon group having 6 to 20 carbon atoms and having at least one glycidyl group; and n is an integer of 1 to 4, and (b-2) 95 to 50% by mole of at least one monomer selected from the group consisting of acrylamide monomers, vinylpyrrolidones, acrylic acid esters and methacrylic acid esters, the monomer mixture being graft-copolymerized with the polyolefin. The modified polyolefin, which uses monomers having good compatibility with the reactive monomers as a modifier, have high reactivity and high reaction efficiency since homopolymerization of the reactive monomers is prevented and reaction sites are uniformly distributed in the polyolefin. When melt-kneaded with other polymers, the modified polyolefin thus has excellent compatibility therewith and are useful as a modifier for various engineering plastics.
