ABSTRACT:
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.
