Patent ID: 7015283

Claim:
A thermoplastic composition comprising: (A) an isotactic polypropylene having a melting point of at least 110° C.; (B) a polyamide; (C) at least 2% by weight, based on the total polymer weight of the thermoplastic composition, of a grafted functionalized propylene-based elastomer having isotactic crystallinity, a heat of fusion of less than 40 J/g, and a melting point of less than 110° C.; and containing at least 0.25% by weight, based on the total weight of the propylene-based elastomer, of maleic anhydride-derived units; and optionally (D) an ungrafted polyolefin having a melting point of less than 100 ° C.; wherein the combined wt % of (A) and (B) is at least 70%, based on the total polymer weight of the thermoplastic composition, and the combined wt % of (C) and (D) is at least 8% based on the total polymer weight of the thermoplastic composition.
