Abstract

A method of preparing a sterile article is disclosed. An article is prepared from a polymer into which is incorporated a stabilizer having the general formula: where each A is independently selected from E, OR, SR, and CO-R, and can join the aromatic ring to form an additional ring, E is R or R(OCH2R'CH)n, G is E, CO-R, -C(E)H-O-R, C(OE)(H)-O-R, -C(E)(R')R''-OR, -C(E)(R')-R''-CO-OR, C(OE)(R')-E''-COOR, -C(OE)R''-O-R, -C(OE)HR, or -C(OE)R2, J is A, each R is independently selected from H, R', R''OR', R''COOR', R''C(OR')R', or R''C(OR')R''OR', each R' is independently selected from alkyl from C1 to C24, aryl from C6 to C24, alkaryl from C7 to C24, and aralkyl from C7 to C24, R' is H or R', R'' is alkylene from C1 to C24, arylene from C6 to C24, alkarylene from C7 to C24, or aralkylene from C7 to C24, m is 1 to 7, and n is 1 to 20. The article is exposed to gamma radiation; it yellows less after irradiation than it otherwise would.
