摘要

采用定时取样研究了以过硫酸钾-亚硫酸氢钠为引发剂，对甲氧基苯辛基二甲基烯丙基氯化铵(ADMAAC)和丙烯酰胺（AM)在水溶液中的共聚反应动力学，测定了相应的聚合速率方程、聚合表观活化能；采用阴阳离子相互作用测定残余ADMAAC的含量，紫外分光光度法测定残余AM的含量，根据单体投料量和残余量差值，得到低转化率下共聚物的组成，按Kelem-Tudos法得到两单体竞聚率。实验结果表明：聚合反应温度在40℃下，聚合速率方程为：

= K [M]

1.241

[KPS]

0.52

[SHS]

0.55

；根据Arrhenius经验公式计算出对甲氧基苯辛基二甲基烯丙基氯化铵(ADMAAC)和丙烯酰胺(AM)共聚的表观活化能为73. 85kJ/mol，高于AM水溶液均聚合的活化能E

(70.32kJ/mol)；两种单体的竞聚率为

ADMAAC

= 0. 197、

= 4.503，为ADMAAC-AM 共聚合反应控制确定了重要的动力学参数。两单体的竞聚率的积小于1，ADMAAC与AM共聚合行为类型是一种无恒比点的非理想共聚行为，共聚物组成曲线，在对角线下方。

Abstract

The kinetics of polymerization of p-methoxybenzeneoctyl dimethyl allyl ammonium chloride (ADMAAC) and acrylamide (AM) initiated by potassium persulfate-sodium bisulfate redox complex in aqueous solution was studied by egular sampling. The polymerization rate equation and apparent activation energy was measured. The content of residual ADMAAC was determined by interaction anion and cation

and the content of residual AM was determined by UV spectrophotometry

and the composition of copolymer at low conversion was obtained by the difference value of input content and residual content of monomer

and the reactivity ratios of monomers in polymerization were obtained by Kelen-Tudos method. The results show that when the polymerization temperature is 40℃

the polymerization rate equation is

= K [M]

1.241

[KPS]

0.52

[SHS]

0.55

. The apparent activation energy is 73. 85kJ/mol

which Is higher than the activation energy Ea (70. 32 kj/mol) of AM aqueous solution homopolymerization

according to the experience formula of Arrhenius

and the values of reactivity ratios are

ADMAAC

= 0.197、

= 4. 503. The important kinetic parameters for controlling of ADMAAC-AM copolymerization reaction is determined. The product of reactivity ratio of two monomers is less than 1

the copolymerization behavior type of ADMAAC and AM is a non-ideal copolymerization behavior without azeotropic point

the copolymer composition curve below the diagonal.
