    摘要: The invention relates to mixed esters of phosphorous or phosphoric acid having on the one hand open chain polyalcohols and on the other hand long chain alkyl compounds with activated hydrogen, for example, alcohols, mercaptans and amines. The compounds are suitable as light and heat stabilizers for polyolefins and for chlorine-containing thermoplastic compositions and are furthermore distinguished by a high resistance to hydrolysis.

    摘要: The invention provides novel derivatives of 2,2-dimethyl-6,6-dialkyl-4-hydroxy-4'-carbamoyl-piperidines which carry a substituent at the amide nitrogen atom, and optionally a further substituent at the ring nitrogen atom, and a process for preparing these compounds.The products, optionally in the form of salts, are used for stabilizing thermoplastics against the damaging influence of light.
