ABSTRACT:
An embrittlement-resistant polymer composition, including: (a) a visbroken polymer composition comprising a crystalline, random copolymer of propylene and either ethylene or C.sub.4 -C.sub.10 1-olefins, and (b) an siloxane which is effective to improve the radiation resistance of the composition. Optional components include an acid neutralizing agent, and a sorbitol-based clarifier compound. The composition may be used to manufacture medical articles and food packaging material which must be sterilized, either by irradiation or by autoclaving.
