摘要
针对丙烯酰胺 (AM )及其衍生物在生产实际中易发生自聚的特点 ,很有必要研究一种阻聚剂来缓解此种现象。为此用沉淀法研究了 1,4-对位苯醌、邻苯二胺、1,4-萘醌、吩噻嗪、对 -叔丁基邻苯二酚五类物质在N2 保护条件下 ,过硫酸铵作引发剂对丙烯酰胺自由基聚合产生的阻聚效应 ,考察了温度、加量对反应体系的影响。结果表明 ,在此五类物质中吩噻嗪对AM的自由基聚合产生较强的阻聚能力且对产物的分子量影响较小。
It is necessary to find out an inhibitor to slow down the spontaneous polymerization of acrylamide(AM)and its derivatives because it often occurs in the practical application. The inhibiting effects of five compounds,such as 1,4-benzoqhinone,o-phenylenediamine,1,4-naphthoquinone,phenothiazine,and p-tert-butyl pyrocatechol on radical polymerization of AM,which was initiated by ammonium persulfate in presence of nitrogen gas,have been investigated by precipitation method. Also the influence of temperature and the quantities of inhibitors on the reaction system has been discussed. Results indicate that the phenothiazine has strong capability to inhibit the radical polymerization of AM and has a little effect on the molecular weight of the products.
