摘要

以丙烯酰胺(AM)、(2-甲基丙烯酰氧乙基)三甲基氯化铵(MADQUAT)为单体

以(NH4)2S2O8/NaHSO3为引发剂

在较低的单体浓度下采用反相微乳液聚合方法进行共聚.采用Kelen-Tüdos(简称K-T)法和Yezrielev-Brokhina-Roskin(简称YBR)法计算得出AM

MADQUAT的竞聚率分别为r1=0.63

r2=1.12.利用测得的竞聚率数据

通过计算机程序计算了共聚物的瞬时组成、平均组成

并研究了在反相微乳液中合成的共聚物的序列分布及平均序列长度.研究结果表明:AM/MADQUAT反相微乳液共聚合趋于无规共聚

共聚物在低转化率时瞬时其组成与平均组成吻合的相对较好.

Abstract

Binary polymerizations of AM-MADQUAT by inverse microemulsion copolymerization with low monomer concentration and using(NH4)2S2O8/NaHSO3 as redox were studied.Reactivity ratios of AM/MADQUAT in inverse microemulsion have been calculated by the methods of Kelen-Tüdos(K-T) and Yezrielev-Brokhina-Roskin(YBR)

being r1=0.63 and r2=1.12 respectively.Using the data of reactivity ratio

instantaneous composition

average composition

sequence distribution and average sequence length of the copolymers were calculated.The results indicate that the inverse microemulsion tends to random copolymerization

and that

at the early stage of the inverse microemulsion copolymerization

the instantaneous composition of the copolymers has a lower drift from average composition.
