Abstract: When replacing the low molecular mercaptan used as a catalyst in the known process for preparing condensation products of phenols and acetoacetic acid esters by an n-alkyl mercaptan having of from 8 to 20 carbon atoms, the yield is improved and the reaction time reduced, while the working up of the reaction batch is simultaneously improved.

Abstract: The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure (I) that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a polyepoxide. The new compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly- alpha -olefins.

Abstract: The invention relates to copolymers of polyalkyl piperidines which are substituted by a polymerizable group and which have the formula with olefinic comonomers such as ethylene, styrene, vinyl acetate, acrylates or methacrylates. The copolymers which have a molecular weight of from 1,000 to 10,000 are used as light stabilizers for synthetic polymers which do not migrate to the surface of the polymers.

Abstract: 1. Solid phosphorous acid ester preparations having an improved stabilizing effect in polyolefin plastic materials, comprising from 20 to 97 weight % of a known, solid organic phosphorous acid ester stabilizer for a plastic material, and form 80 to 3 weight % of a wax selected from the group consisting of natural or partially synthetic ester waxes, amide waxes, esters of polyolefin wax oxidates and wax-like esters of long chain phosphorous acids.
