GAMMA RADIATION RESISTANT CARBONATE POLYMER COMPOSITIONS

This invention relates to carbonate polymer compositions which are rendered gamma ray resistant by the incorporation of 500 to 50,000 ppm of one or more polyether polyols. Compared to the controls, the compositions of the invention have a reduced yellowing after exposure to cobalt 60 radiation.
