ABSTRACT:
Ultra violet light resistant polycarbonates are produced having processing or heat stability by adding compatible UV absorbing compounds and aromatic sulfonimides. The UV absorbing compounds are used in amounts from about 0.01 to about 5.0% by weight and the sulfonimides are used in an amount from about 0.0001 to about 10.0%. The preferred UV absorber is 2-(2'-hydroxy-5'-t-octylphenyl)-benzotriazole. The preferred sulfonimide is N-(p-tolylsulfonyl)-p-toluenesulfonimide.
