【摘要】 介绍了 N,N 二甲基乙基丙烯酰胺 (CA)同丙烯酰胺 (AM)水溶液的共聚合反应。利用共聚物组成微分方程重排 ,采用斜解式作图法测定了两单体竞聚率 ,试验数据用微机处理作图测得竞聚率值 r1=0 1 1 6 ,r2 =3 6 1 0。为 N,N 二甲基乙基丙烯酰胺同丙烯酰胺共聚合反应控制确定了重要的动力学参数 ,这对由此两种单体共聚合形成某种阳离子度聚合物时是有重要意义的。更多还原

【Abstract】 The copolymerization between N,N dimethyl ethyl acrylamide(CA) and acrylamide(AM) is made The reactivity ratio of two monomers (CA and AM) is measured respectively:r 1=0 116 and r 2=3 610 Some kinetic parameters are determined for copolymerization control This is important to formulate cationic polymers with certain cationic concentration by copolymerizing CA and AM更多还原
