Polychloroethylene, e.g., trichloroethylene and perchloroethylene, is stabilized with a stabilizing amount of a stable free radical stabilizer, e.g., a material having the 2,2,6,6-tetra(lower alkyl)-1-piperidinyloxy-yl free radical group, such as 2,2,6,6-tetramethyl-4-hydroxy-1-piperidinyloxy.
聚氯乙烯,例如三氯乙烯和四氯乙烯,通过添加稳定的自由基稳定剂来稳定,例如含有2,2,6,6-四(较低烷基)-1-哌啶氧自由基基团的材料,如2,2,6,6-四甲基-4-羟基-1-哌啶氧自由基。
