ADHESIVE FOR METAL-VINYL CHLORIDE-BASED RESIN AND METAL-VINYL CHLORIDE-BASED RESIN LAMINATE

摘要

PROBLEM TO BE SOLVED: To obtain an adhesive of epoxidized styrene-based thermoplastic elastomer for metal-vinyl chloride-based resin, and a metal-vinyl chloride-based laminate where the metallic base layer is bonded to the vinyl chloride-based resin layer via a layer of the adhesive. SOLUTION: This adhesive consists of a block copolymer C which is composed of polymer block A consisting mainly of a styrene-based compound and polymer block B consisting mainly of a conjugated diene compound which may be partially hydrogenated, where the double bond of the conjugated diene compound is epoxidized to form an epoxidized styrene-based thermoplastic elastomer D. Degree of epoxidation of the epoxidized styrene-based thermoplastic elastomer D is preferably in the range of 10 to 40%.
