Abstract

Procedure for obtaining moldable masses of polycarbonates based on aromatic dihydroxy compounds, with ultraviolet light absorbing properties, characterized in that 0.05 to 10% by weight of a homo- or copolymer is copolymerized with the starting products. UV absorbing groups of general formula **(See formula)** wherein R1 is hydrogen, C1 to C4 alkyl, R2 is alkyl, C1 to C12 cycloalkyl, and R3 is hydrogen, C1 to C4 alkyl, methoxy, or halogen.
