New polyalkylated 4-aminopiperidine derivatives contain in their molecule two or three piperidine rings, each having two alkyl substituents at both the 2- and the 6- positions, optionally having substituents at the 1- and 3- positions and having an amino substituent at the 4- position. The piperidine rings are joined together by attachment of the 4-amino substituents through, where there are two piperidine rings, a polyalkylene, polyether or polyester chain, or through, where there are three piperidine rings, an isocyanurate or glycerol system. These compounds and their acid addition salts are useful as stabilizers for synthetic polymers.
新的聚烷基化4-氨基哌啶衍生物在其分子中包含两个或三个哌啶环,每个哌啶环在2-和6-位置都有两个烷基取代基,可选地在1-和3-位置有取代基,并在4-位置有氨基取代基。哌啶环通过4-氨基取代基的连接相互结合,当有两个哌啶环时,通过聚烷烯、聚醚或聚酯链连接,当有三个哌啶环时,通过异氰酸酯或甘油系统连接。这些化合物及其酸盐加合物可用作合成聚合物的稳定剂。
