【摘要】 <正> 近年来氮氧稳定自由基化合物已越来越引起人们的注意,但是带有四甲基哌啶氮氧自由基的高分子化合物的合成和应用仍然研究得不多,Keana等用甲基丙烯酰氧基氮氧自由基以格氏试剂引发聚合得到低分子量的氮氧自由基聚合物,或将聚甲基丙烯酰氯和四甲基哌啶醇的氮氧自由基反应而得到相应的氮氧自由基聚合物,Kurosaki等则使更多还原

【Abstract】 Polymethacryloyl 2, 2, 6, 6-tetramethylpiperidine and polyacryloyl 2, 2, 6, 6-tetra-methylpiperidine and copolymers of styreneacryloyl 2, 2, 6, 6-tetramethylpiperidine were preprared. Corresponding polymeric nitroxyls were obtained by .oxidation of these polymers containing tetramethylpiperdine. When these polymeric nitroxyls used as inhibitor in the synthetic process of unsaturated ester, allylmethacrylate and glycol bis-roethacrylate were prepared with high yield.更多还原
