  Novel derivatives of 4-amino-2,6-dimethylpiperidine have additional methyl or substituted-methyl substituents at positions 2 and 6, and a carboxylate ester substituent at position 4. Positions 1 and 3, and the amino group at position 4, can optionally also be substituted. These derivatives are useful for stabilizing synthetic polymers, especially polyolefins, polyamides and polyurethanes, against photo- and thermal-deterioration, generally in an amount of 0.01 - 5.0% by weight based on the polymer.

  4-氨基-2,6-二甲基哌啶的新型衍生物在2和6位置上具有额外的甲基或取代甲基取代基，并在4位置上具有羧酸酯取代基。位置1和3以及4位置的氨基基团也可以选择性地被取代。这些衍生物对于稳定合成聚合物，特别是聚烯烃、聚酰胺和聚氨酯，抵抗光和热恶化非常有用，通常按聚合物重量的0.01-5.0％的比例使用。

  Polymers containing polyalkylpiperidines, preparation and use thereof as stabilizers for synthetic polymer compositions are described. In said polymer, sterically hindered polyalkylpiperidines are laterally linked to the main chain. The polymers are distinguished by an improved stabilizing effect in various synthetic polymer compositions, such as polyolefins, against light- and/or heat-induced deterioration thereof. The polyalkylpiperidine-containing polymers of the invention are hardly volatile upon heat-processing or during storage of shaped articles containing said polymers, and are resistant to extraction with solvents.
