The results indicate that the quantity of the chain transfer agent 2% the total quantity of cationic monomer is added when the copolymerization has been 40mins. The reaction product has the high conversion percent and better dissolving power.

• 研究结果表明,链转移剂加入量为反应体系单体总重量的2%25,加入时间为反应开始聚合后40分钟的条件下聚合所得阳离子聚丙烯酰胺有较高的转化率和很好的溶解性。
