| 摘 要： | 本文描述了在模拟聚合条件下几种羟胺类化合物在烯烃单体自由基聚合反应中形成氮氧自由基的ESR研究。结果表明在引发剂BPO和AIBN存在下,可以检测到由各母体羟胶生成对应的氮氧自由基,测量了各自由基的超精细偶合常数。提出了羟胺类化合物的可能阻聚机理。

| Abstract: | The nitroxidc radicals produced from hydroxylamines in the radical polymerization of vinyl monomers have been studied by ESR technique. The results show that the nitroxidc radicals formed from their parent hydroxylamines can be detected in the presence of initiators BPO and AIBN. From these experimental results, the inhibition mechanism for the polymerization is proposed and discussed. |
