摘要
以丙烯酸钠为单体,在氧化-还原引发体系下,采用低温水溶液聚合方法,制备出分子量从几百万至上千万的高分子量产物,用作增稠剂和絮凝剂有较好的效果。
The synthesis of high molecular weight polyacrylicsodium and applications are reported in this paper. Using low temperature aqueous solution polymerization with a redox initiator, the molecular weight of the product may range from a few millions to over ten millions. It could be used as thickening agent and flocculant.
