  Sterically hindered piperidines having at least 5 alkyl groups in ring positions 2,3,5 and 6 are usable as light-stabilizers for organic polymers. The nitrogen may be unsubstituted or may bear a mono- to tetravalent substituent. The compounds can be synthesized by a Wolf-Kishner reduction of polyalkyl 4-oxopiperidines optionally followed by a N-substitution reaction in a second step. The stabilizers are added to the polymers in an amount of from 0.01 to 5% by weight. Preferred is the stabilization of polyolefins, styrene polymers, polyamides and polyurethanes.

  具有至少5个烷基基团的立体阻碍哌啶在环的2、3、5和6位可用作有机聚合物的光稳定剂。氮原子可以未取代或带有一价至四价取代基。这些化合物可以通过Wolf-Kishner还原多烷基4-氧代哌啶，可选择在第二步进行N-取代反应来合成。稳定剂以0.01至5%的重量添加到聚合物中。首选的是对聚烯烃、苯乙烯聚合物、聚酰胺和聚氨酯进行稳定。
