Ethylenically unsaturated compounds containing 1-hydroxycarbyloxy-2,2,6,6-tetramethylpiperidine moieties represent reactable stabilizers which may be homopolymerized or copolymerized with other ethylenically saturated monomers to form non-migrating, light stabilizers which are very effective in stabilizing polyolefins and other polymer substrates against the deleterious effects of actinic light.
含有1-羟基羧氧基-2,2,6,6-四甲基哌啶基团的乙烯不饱和化合物代表可与其他乙烯饱和单体进行均聚或共聚反应的稳定剂,形成非迁移性、光稳定剂,对稳定聚烯烃和其他聚合物基质免受光化学光的有害影响非常有效。
