Patent ID: 7267884

Claim:
An article comprising, or prepared from, a composition which comprises (a) at least one polyamide polymer; and (b) at least one E/X/Y copolymer wherein the article is an oriented film or an oriented fiber that has been drawn at a temperature below the melting point of the polyamide polymer to a draw ratio greater than 10:1; the amount of the E/X/Y copolymer is from 0.1 to 20 weight %, based on the total weight of the composition; E represents copolymerized residues of ethylene; X represents conolymerized residues of at least one comonomer selected from the group consisting of vinyl acetate and alkyl (meth)acrylic esters; Y represents copolymerized residues of one or more comonomers selected from the group consisting of carbon monoxide, sulfur dioxide, acrylonitrile, maleic anhydride, maleic acid diesters, (meth)acrylic acid, maleic acid, maleic acid monoesters, itaconic acid, fumaric acid, fumaric acid monoesters, and salts thereof, glycidyl acrylate, glycidyl methacrylate, and glycidyl vinyl ether; and the amount of X is from 0 to 50 weight % and the amount of Y is from 0 to 35 weight %, based on the total weight of the E/X/Y copolymer, the weight % of X and Y cannot both be 0, and the remainder of the E/X/Y copolymer comprises copolymerized ethylene E.
