The present invention relates to a thermoplastic elastomer composition comprising the following components (A) and (B), and to a composite molded product comprising a resin layer and an elastomer layer containing said composition as the base material. Component (A): 5 to 95% by weight of a styrene type block copolymer or a hydrogenated product thereof, comprising block (a) which is made of a polymer of styrene or a derivative thereof, and block (b) which is made of an isoprene homopolymer or a copolymer of isoprene and butadiene, wherein the total amount of the 1,2-bond and the 3,4-bond in the isoprene polymer part in block (b) is not less than 40% of the total isoprene bond unit. Component (B): 95 to 5% by weight of one or more thermoplastic elastomers which are selected from the group consisting of polyester type thermoplastic elastomers, polyamide type thermoplastic elastomers, and polyurethane type thermoplastic elastomers. The composition of the present invention exhibits excellent heat fusion properties to both an olefin type resin and a nonolefin type resin, and gives a composite molded product having a high peeling strength, comprising said resin and said elastomer. |
