The present invention is an irradiated article made from a composition and of irradiating the composition. The composition comprises a polyamide and a hindered phenol having the formula: <CHEM> wherein: R1 is methyl, ethyl or an alpha-branched alkyl group of from 3-10 carbons, R2 is hydrogen, methyl, ethyl or an alpha-branched alkyl group of from 3-10 carbons, x is from 2-6, n is from 2-6, it is recognized that when n is greater than one, the alkyl phenol groups can vary in structure, and Z is selected from the group consisting of alkylenes, arylenes, cyanurates, esters, amines, phosphorus, oxygens, sulfur, amides wherein the basic amide structure is -@-@-, and mixtures thereof. i |
