WATER-BASED RESIN DISPERSION

摘要

PROBLEM TO BE SOLVED: To obtain a water-based resin dispersion capable of giving an adhesive exhibiting high bond strength and intended for bonding polyolefins. SOLUTION: This water-based resin dispersion is obtained by dispersing in water (A) an olefin-based block copolymer of the general formula (I): PO-f-R (PO is a polyolefin segment composed of recurring unit derived from a 2-20C olefin and having a weight-average molecular weight of >=2,000; f is an ether linkage, ester linkage or amido linkage; and R is a functional segment having come from chain polymerization reaction and comprising recurring unit >=500 in weight-average molecular weight) or (C) an olefin-based polymer composition comprising the component A and a thermoplastic resin B other than the component A.
