Abstract

The present invention is a thermoplastic polymer composition which contains 10-120 parts by mass of a polar group-containing polypropylene resin (B) per 100 parts by mass of a thermoplastic elastomer (A) that is a block copolymer having a polymer block containing an aromatic vinyl compound unit and a polymer block composed of a conjugated diene unit having 40% by mole or more of 1,2-bonds and 3,4-bonds in total, or a hydrogenated product of the block copolymer (provided that a thermoplastic polymer composition containing 1 part by mass or more of a polyvinyl acetal resin is excluded). This thermoplastic polymer composition is able to be bonded with a ceramic, a metal or a synthetic resin without requiring a primer treatment, and has excellent flexibility, mechanical characteristics, moldability, heat resistance and storage stability.
