摘　　要：通过操作简便、应用广泛的水溶液聚合法,制备了粘均分子量约为1500~3000聚丙烯酸钠。研究表明,聚丙烯酸钠的相对分子量随着引发剂用量以及链转移剂用量的增加而减小。相应聚丙烯酸钠(分子量为2000)的减水率达到22.8%,高于市场常用萘系减水剂,表现出优异的应用潜力。Sodium polyacrylate(PAANa)with a viscosity average molecular weight from 1500 to 3000 is synthesized by a facile,easily operated route of water solution polymerization.The result shows that with the increase of the dosage of initiator and chain transfer agent,the relative molecular weight decreases.By using PAANa as water-reducing reagent,the water-reducing efficiency reaches 22.8%,demonstrating its potential application in water-reducing materials.
