摘要
本文主要研究了用甲基丙烯酸N,N一二甲胺基乙酯(DMAEMA)与过硫酰钾(K_2S_2O_8)组成的引发体系,引发丙烯酰胺的聚合,并用正交设计法优选了最佳反应条件,在此条件下聚合可得到分子量两千万的聚丙烯酰胺。
Abstract The polymerization of acrylamide initiated by a combined system of N, N-dimethyl aminoethylene methacrylate and potassium persulfate was studied.
Super-high molecular weight (2x107)polyacrylamide were obtained by using such a initiation system.
