摘要

研究了醋酸乙烯酯 (VAC)与甲基丙烯酰氧乙基三甲基氯化铵 (DMC)无皂乳液共聚合动力学

考察了引发剂偶氮二异丁基脒盐酸盐 (AIBI)浓度、单体浓度、温度等因素对聚合反应速率的影响

得到单体总浓度和引发剂浓度影响反应速率的动力学方程为:Rp=k1[M]0.63[AIBA]1.0 ;各单体浓度影响反应速率的动力学方程为:Rp=k2[VAC]0.16 [DMC]0.89.聚合表观活化能为 44.01kJ·mol-1

初步探讨了聚合反应机理.

Abstract

Soap-free Cationic Emulsion Copolymerization of vinyl-acetate (VAC) with methacryloyloxyethyl trimethylammonium chloride (DMC) has been studied．The factors influencing the reaction rate were discussed

such as the comonomer concentration

initiator concentration

temperature

etc．The result of kinetics showed that the influence of comonomer concentration and initiator concentration on the rate of coplymerization could be expressed as：Rp=k1 [M]0.63 [AIBA]1.0

the reaction order of VAC and DMC was：Rp=k2[VAC]0.16[DMC]0.89

and the apparent activation energy of polymerization was 44.01 kJ·mol-1. The mechanism of the soap free emulsion compolymerization was also discussed.
