Abstract: 7-[N-(2-alkylidenimino-isobutylamino)]-1,3,5-triazaadamantanes and 7-[N-(2-arylidenimino-isobutylamino)]-1,3,5-triazaadamantane are prepared from 7-amino-1,3,5-triazaadamantane by two condensation steps. The new compounds are very good stabilizers against decomposition of polymers by heat and UV-light.

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: The invention provides novel esters of glycerol, in which one of the OH groups of the glycerol is esterified with a phenolcarboxylic acid, while the two other OH groups are esterified with phosphoric or phosphorous acid, substituted by long-chain alcohols, amines, mercaptans or phenol compounds. The products are suitable as light and heat stabilizers for plastics. They are distinguished by a high resistance to hydrolysis and extraction.
