Patent ID: 7199188

Claim:
A toughened polyamide composition, comprising: (1) from about 50 wt % to about 98 wt % of a polyamide resin, based on the total weight of the polyamide composition, and (2) from about 2 wt % to about 50 wt % of an impact modifier composition, based on the total weight of the polyamide composition, said impact modifier composition comprising (a) from about 10 wt % to about 50 wt % of a first polymer, based on the total weight of said impact modifier composition, wherein said first polymer is a copolymer prepared by high pressure free radical copolymerization comprising copolymerized units of ethylene and a comonomer selected from the group consisting of maleic acid monoesters, maleic acid diesters, fumaric acid monoesters, and mixtures thereof, and wherein said first polymer comprises from about 3 wt % to about 15 wt % of said comonomer, and (b) from about 50 wt % to about 90 wt % of a second polymer, based on the total weight of said impact modifier composition, wherein said second polymer is a copolymer of ethylene and an alpha-olefins prepared using metallocene catalysts.
