IRRADIATION OF A POLYAMIDE COMPOSITION

摘要

ABSTRACT OF THE DISCLOSUREThe present invention is an irradiated article made froma composition and a method of irradiating the composition. Thecomposition comprises a polyamide and a hindered phenol havingthe formula:wherein:R1 is methyl, ethyl or an alpha-branched alkyl groupof from 3-10 carbons,R2 is hydrogen, methyl, ethyl or an alpha-branchedalkyl group of from 3-10 carbons,x is from 2-6,n is from 2-6, it being recognized that when n isgreater than one, the alkyl phenol groups can vary instructure, andz 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.
