Abstract: PROBLEM TO BE SOLVED: To obtain the subject new additive mixture capable of remarkably reducing the release of the decomposition products of dibenzylidene sorbitol or its derivative, when its mixture of a polymer is processed, by adding an amide functional compound to the dibenzylidene sorbitol or its derivative. SOLUTION: This additive mixture comprises (A) dibenzylidene sorbitol or its derivative [preferably 1,3:2,4-di(benzylidene)-D-sorbitol, etc.,] and (B) an amide functional compound (preferably bisstearoyl ethylenediamine, bislauroyl ethylenediamine, etc.,) preferably in a B:A mixing ratio of 1.5:l to 1:1.5 as basic components. When added to a polymer, the objective mixture is preferably added so that the component B is contained in a concentration of 0.1-1wt.% based on the whole amount of the polymer. The polymer to be mixed with the objective mixture includes polyolefins.

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.

Abstract: Additive mixture with nucleating properties for plastic materials - contains dibenzylidene sorbitol or a derivative thereof as a nucleating agent (A) and amido-functional compounds (B). Also claimed are (i) plastic materials containing these mixtures and (ii) the use of (B) in these materials for scavenging aldehydes formed by degradation of the nucleating agent by means of adsorption, absorption and/or chemical reaction.
