【摘要】 利用RAFT聚合法合成了一系列窄分布的低分子量聚丙烯酰胺,研究了溶剂、RAFT试剂类型及用量对单体转化率、聚合物分子量和分子量分布的影响.可以看出聚合反应具有活性可控的特征,丙酮为更合适的溶剂,RAFT 1为更合适的RAFT试剂,且RAFT 1能实现不同分子量PAM的活性控制.更多还原

【Abstract】 A series of polyacrylamide with low molecular weight and narrow molecular weight distribution wereprepared by RAFT Polymerization.The effect of solvent and RAFT on monomer conversion,polymer molecularweight and molecular weight distribution were investigated.The results indicated that polymerization showed" living"/controlled characteristics,the optimum solvent and RAFT were acetone and RAFT 1.更多还原
