1-Hydrocarbyloxy substituted hindered amine compounds which also contain a reactive functional group such as hydroxy, amino, oxirane or carboxyl can be chemically attached to selected polymer substrates by condensation reactions to give polymers containing a chemically-bonded, non-migrating stabilizer having excellent stabilization efficacy for protecting said polymer substrate from the adverse effects of actinic light.
1-Hydrocarbyloxy 取代的受阻胺化合物还含有羟基、氨基、环氧乙烷或羧基等活性官能团,可通过缩合反应与选定的聚合物基材发生化学键合,从而得到含有化学键合的非迁移稳定剂的聚合物,该稳定剂具有优异的稳定效果,可保护所述聚合物基材免受光辐射的不利影响。
