Blends of polycarbonate with ABS resins are effectively stabilized by a combination of selected non-basic hindered amines containing the 3,3,5,5-tetramethyl-2-oxo-1-piperazinyl moiety and UV absorbers such as benzotriazoles, s-triazines and benzophenones, particularly the benzotriazoles and s-triazines. |
