PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition having high flexibility and excellent thermal deformation resistance and moldability and especially excellent in the compatibility with a resin having a polar group, and to provide a thermoplastic resin composition using the same. SOLUTION: The thermoplastic elastomer composition is obtained by melting and kneading a composition containing 5-300 pts.wt. of a rubber softener (b), 0.01-3 pts.wt. of an organic peroxide (c) and 1-80 pts.wt. of a liquid polybutadiene having a hydroxyl group (d) on the terminal with 100 pts.wt. of an elastomer (a) prepared by mixing a hydrogenated material (a-1) obtained by hydrogenating≥90% of a conjugated diene block of a block copolymer composed of at least two polymer blocks A composed mainly of an aromatic vinyl compound and at least one polymer block B composed mainly of a conjugated diene compound and a hydrogenated material (a-2) having a hydrogenation ratio of <90% at an (a-1)/(a-2) ratio of 5-95/95-5 (wt.%). The thermoplastic resin composition using the elastomer composition is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
