Patent ID: 8378035

Claim:
A thermoplastic elastomer composition comprising a modified polyamide resin (C) and a modified rubber (D) dispersed in the modified polyamide resin (C), the modified polyamide resin (C) being a resin obtained by melt-blending a polyamide resin (A) and a compound (B) capable of reacting with a terminal amino group of a polyamide resin, wherein the modified rubber (D) has an acid anhydride group or epoxy group and is dynamically cross-linked by a compound (F) having at least one disulfide bond and at least two amino groups; wherein the modified rubber (D) is dynamically cross-linked by the compound (F) having at least one disulfide bond and at least two amino groups and a compound (G) having at least two amino groups and having no disulfide bond.
