Abstract: The present invention relates to additive mixtures having a nucleating action for plastic compositions, comprising nucleating agents based on dibenzylidenesorbitol, or derivatives thereof, and amido-functional compounds. The aldehydes formed from the nucleating agents by decomposition during processing and use of the plastics treated therewith are collected and bound by adsorption, absorption and/or chemical reaction.

Abstract: The invention relates to stabilisers for plastics which increase their molar weight as a result of a photochemical reaction. Said stabilisers are compounds of the general formula (I), the different substituents having the meaning defined in the description. Said novel stabilisers are particularly suitable to act as light stabilisers for polymers.
