Abstract:
A heat-fusion composition for molding into multi-layers comprising 20 to 80% by weight of a block copolymer having epoxy groups (a), which is an epoxidized block copolymer obtained by epoxiding (i) a block copolymer comprising a polymer block mainly composed of a vinyl aromatic hydrocarbon compound and a polymer block mainly composed of a conjugalated diene compound, or (ii) the hydrogenated product of said block copolymer, wherein the epoxidation is effected by peroxidation of the ethylenic double bonds and the epoxy equivalent of the epoxidized block copolymer is 140 to 10,000, and 80% to 20% by weight of at least one kind of thermoplastic elastomer (b) selected from the group consisting of styrene elastomers, polyurethane elastomer, polyester elastomers, polyamide elastomers, polyolefin elastomers and polyvinyl chloride elastomers, the combined content of (a) and (b) being 100% by weight.
