THERMOPLASTIC RESIN COMPOSITION

摘要

The present invention improves the low temperature endurance of a thermoplastic elastomer composition comprising a polyamide resin and a modified rubber. A thermoplastic elastomer composition which comprises a polyamide resin and a modified rubber having an acid anhydride group or an epoxy group, characterized in that the modified rubber having an acid anhydride group or an epoxy group is modified with a secondary amine. The secondary amine is preferably a compound having a structural formula R1-NH-R2 (In the formula, R1 is a C1-30 straight chain alkyl group, and R2 is a C1-30 hydrocarbon group or a C1-30 hydrocarbon group having a hydroxyl group, a sulphonyl group, a carbonyl group or an ether linkage).
