摘要/Abstract

摘要：

在氯化1-烯丙基-3-甲基咪唑（[AMIM]Cl）离子液体中，采用原子转移自由基聚合（ATRP）技术，以CuBr/乙二胺为催化体系，合成了分子量分布窄的聚甲基丙烯酸甲酯（PMMA）分子。探索了聚合反应条件对PMMA分子量大小及分布的影响。通过GPC对PMMA分子量大小及分布进行测试，结果表明，在[AMIM]Cl离子液体体系中的ATRP反应，反应时间是控制PMMA分子量大小主要因素，而催化体系是控制PMMA分子量分布宽窄的决定性因素。通过优化反应条件可以设计聚合物分子量的大小和分布，可以实现对聚合物分子量的精确控制，使合成的聚合物材料满足在化工医药中的特定应用。

Abstract:

The narrow molecular weight distribution of poly methyl methacrylate (PMMA) was synthesized by atom transfer radical polymerization (ATRP) in the ionic liquid 1-allyl-3-methylimidazolium chloride ([AMIM]Cl). Dibromo ethyl isobutyrate(2-Ebib) was used as the initiator and CuBr/ethanediamine was the catalytic system.Polymerization conditions were explored on molecular weight and distribution of PMMA.Molecular weight size and molecular weight size distribution were determined by GPC.The results showed that the molecular weight size of PMMA was mainly controlled by reaction time and the molecular weight size distribution of PMMA was controlled by catalyst system.Design of the molecular weight size and distribution of polymer could carry out by optimizing the reaction conditions to achieve precise control of polymers molecular weight.It has a perfect application potential in the field of chemical medicine.
