Modifier for polyolefin resin

摘要

Provided are a modifier for polyolefin resin which imparts excellent wettability for water, etc. to a polyolefin resin substrate without decreasing the resin property of the polyolefin resin substrate composed of polyolefin resin, and a polyolefin resin composition containing the modifier and a polyolefin resin. The present invention relates to a modifier for polyolefin resin (K) containing a copolymer (X) having a polyolefin (A) and an unsaturated dicarboxylic acid (anhydride) (B) as a constitutional unit and having an acid value of 50 to 250 mg KOH/g.

主权项

1. A modifier for polyolefin resin (K) containing a copolymer (X) having a polyolefin (A), an unsaturated dicarboxylic acid (anhydride) (B) and an unsaturated aliphatic hydrocarbon (C) as a constitutional unit and having an acid value of 50 to 250 mg KOH/g,
wherein said (C) is a linear α-olefin or a branched α-olefin having a carbon number of 6 to 36, and wherein said (X) is a graft copolymer having said (A) as a backbone and a (co)polymer of said (B) and said (C) as its side chain.
