A thermoplastic polymer composition comprises: a thermoplastic polymer (a) having polarity on the main chain of the molecule thereof, and a modified block copolymer (b) of a block copolymer comprising: at least one polybutadiene block (B) having a degree of vinylization of not more than 30%, and at least one polymer block (D) comprising units from isoprene and butadiene in a ratio by weight of isoprene/butadiene of 30/70 to 100/0 and having a degree of vinylization of not more than 30%, said polybutadiene block (B) and said polymer block (D) each has a degree of unsaturation of not more than 30%, to said block copolymer a molecular unit containing a carboxyl acid group or derivatives thereof having added, the ratio by weight between said component (a) and said component (b), (a)/(b), being in a range of 2/98 to 98/2.
