ABSTRACT:
Certain essentially phenol antioxidant-free stabilizer systems that comprise either a binary hindered amine/hydroxylamine or nitrone or amine oxide or benzofuranone system or a ternary hindered amine/hydroxylamine or nitrone or amine oxide or benzofuranone/organic phosphite or phosphonite system are especially effective towards protecting polyolefins against the deleterious effects of gamma irradiation. Polyolefin articles such as medical packaging, hospital garments, draperies, woven and non-woven fiber products, surgery utensils, blow-molded I.V. bottles, hypodermic syringes, needle shields, laboratory ware such as trays, funnels, Petri dishes and filters, and hygiene related articles may be sterilized with gamma irradiation and are stabilized according to the present invention.
