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