Abstract of the Disclosure Esters and amides from 4-hydroxy-and 4-amino-polyalkyl- piperidines and hydroxybenzylmalonic acids substituted at the central carbon atom with an organic residue, preferably alkyl-, esteralkyl- or phosphonoalkyl-groups, are excellent stabilisers for organic polymers, especially for polyolefins. They protect the polymers, as well against light degradation as against thermo-oxidative degradation. The compounds can be prepared by hydroxybenzylation of the corresponding derivatives of substituted malonic acids. Bis-malonic acid derivatives may be obtained from the mono- malonics by reaction with formaldehyde.
