Patent

CA 2014931

The invention relates to thermoplastic polycarbonate molding compositions which are rendered improved resistance to gamma-radiation by the incorporation therewith of about 0.05 to about 5.0 percent by weight of an ester of poly(alkylene)oxide conforming to (see fig. I) wherein R is a C1-C20 alkyl, aryl or alkylaryl, Y denotes a hydrogen atom or a C1-C6 alkyl radical, and X is about 1 to 40, preferably 5 to 30. The compositions of the invention exhibit excellent resistance to yellowness and formation of haze which commonly characterize gamma irradiated articles molded from polycarbonate.
