摘要

在以过氧化二苯甲酰（BPO）为引发剂、1

10-邻二氮菲（phen）为催化剂配体、十二烷基磺酸钠（SLS）为乳化剂

水分散体系中进行的苯乙烯（St）的反向原子转移自由基聚合体系中

系统地分析了CuBr2/phen络合物、CuBr/phen络合物、SLS和phen在St/水两相中的分配行为

发现CuBr2/phen络合物、CuBr/phen络合物的两相分配系数对温度有一定的依赖性

结合所得的两相分配系数

从理论上分析了CuBr/CuBr2/phen/BPO乳液聚合体系中的"活性"/可控乳液聚合活性种的数目

较详细的讨论了水分散体系中反向ATRP反应的机理

并通过分相后的本体聚合实验

佐证了测得的催化体系的两相分配系数具有一定的指导意义.

Abstract

The partitions coefficients of Cu（Ⅰ）/phen

Cu（Ⅱ）/phen、SLS and phen between the styrene（St）phase and water phase were measured respectively in the reverse atom transfer radical polymerization reaction system of styrene initiated by benzoyl peroxide（BPO）with phenanthroline（phen）as ligand and sodium lauryl sulfate as surfactant.The results indicated that the partition behavior of Cu（Ⅰ）/phen and Cu（Ⅱ）/phen could be affected by the temperature.Based on the partition coefficients measured

the number of controlled active species in the CuBr/CuBr

/phen/BPO reverse ATRP emulsion polymerization system was theoretically calculated

and the reaction mechanism of reverse ATRP was discussed in detail.Though the bulk polymerization after the catalyst partitioning between the St phase and the water phase

we proved that the calculated results was reasonable.
