摘要： The invention relates to thermoplastic molding compositions comprising a polycarbonate resin which is rendered resistant to gamma radiation induced yellowing. It was surprisingly found that the incorporation in the resin of an effective amount of benzylic alcohol or its derivatized versions renders the composition resistant to yellowing. The composition of the invention is suitable for the preparation of molded articles having improved resistance to yellowing and to the formation of haze induced upon exposure to gamma radiation.
