摘要
以乙醇和丙酮为混合溶剂合成了低分子量聚丙烯酰胺 .研究结果表明 :丙烯酰胺在乙醇和丙酮中的沉淀聚合反应时间短 ,转化率达 97%.通过调节乙醇和丙酮的质量比和单体浓度可以获得 (2 .0~ 2 4)×1 0 4的低分子量的聚丙烯酰胺 .
The synthesis of the low molecular weight polyacrylamide was imvestigated in the mixed solvents of ethanol and acetone .The monomer conversion was 97% in short time . The low molecular weight polyacrylamides (viscosity average molecular weight =20000~240000) were obtained by changing the weight ratio ethanol to acetone or the acrylamide concentration.
