ABSTRACT:
1-Hydrocarbyloxy-2,2,6,6-tetramethylpiperidine derivatives of s-triazines having functional groups such as hydroxy, amino, carboxy, epoxy, isocyanate or the like present are capable of chemically bonding with polymer substrates having anhydride, epoxide, alkoxymethylmelamine or isocyanate moieties present. This chemical bonding prevents migration or loss of the stabilizer during subsequent processing or end-use application of the stabilized polymer.
