摘要：
Ethylenically unsaturated compounds containing 1-hydrocarbyloxy-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.
