ABSTRACT:
Piperidine derivatives in which two or three piperidine residues each substituted at the 2- and the 6-position by two methyl groups or by one methyl group and one ethyl group, the piperidine residues being attached by means of substituted alkylene groups, by means of polyoxyalkylene groups (whose oxyalkylene chain is optionally interrupted by one or more phenylene or cyclohexylene groups), by means of substituted isocyanurate groups or by means of glyceryl groups, and acid addition salts thereof are valuable as stabilizers for synthetic polymers.
