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.
1-羟烷氧基-
2,2,6,6-四甲基哌啶衍
生物的s-三嗪具有羟基、
氨基、羧基、环氧、
异氰酸酯或类似官能团的功能基团,能够与具有酸酐、环氧、烷氧甲基
三聚氰胺或
异氰酸酯官能团的聚合物基体进行
化学键合。这种
化学键合可以防止稳定剂在后续加工或最终使用应用中的迁移或丢失。
