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.
本发明涉及一种热塑性弹性体(A),其中每100质量部的热塑性弹性体(A)中含有10-120质量部极性基含量的聚丙烯树脂(B),该聚合物是一种块状共聚物,其中聚合块包含芳香族乙烯化合物单元和由具有40%或更多1,2键和3,4键的共轭二烯单元组成的聚合块,或者是该块状共聚物的氢化产物(前提是不包括含有1质量部或更多聚醛酸乙烯酯树脂的热塑性聚合物组合物)。该热塑性聚合物组合物能够与陶瓷、金属或合成树脂粘接,无需底漆处理,并具有优异的柔韧性、机械特性、成型性、耐热性和贮存稳定性。
