1-Hydrocarbyloxy-2,2,6,6-tetramethyl-piperidine derivatives of s-triazines with functional groups such as hydroxy, amino, carboxy, epoxy, isocyanate or the like which can bind chemically with polymeric substrates with anhydride molecular parts, epoxide, alkoxymethylmelamine or isocyanate, chemical bond which prevents migration or loss of the stabilizer during processing or subsequent use of polymeric materials stabilized with these derivatives. |
