The present invention provides a thermoplastic polymer composition mainly comprising a block copolymer prepared by extending, with a specific polyurethane component, the polymer chain of a block copolymer, which may be hydrogenated, having a polymer block of an aromatic vinyl compound and a polymer block of a conjugated diene. The thermoplastic polymer composition according to the present invention is excellent in handling properties and melt-moldability, because it shows non-tackiness. By using the thermoplastic polymer composition according to the present invention, a molded article having high qualities can be produced with good productivity.
本发明提供了一种热塑性聚合物组合物,其主要成分为嵌段共聚物,该嵌段共聚物的聚合物链可以氢化,并具有芳香族
