| 摘 要： | 本研究从歧化松香中提取的去氢枞酸(DHA)出发,经酰氯化后与丙烯酸(2-羟基)乙酯反应,合成了去氢枞酸丙烯酸乙二醇酯(DHAAGE);并以此为单体,2-溴-异丁酸乙酯(EBr-iB)为引发剂,CuBr/2,2'-联吡啶(2,2'-bipyridine)为催化体系,在90 oC下,利用原子转移聚合(ATRP)法制备了聚去氢枞酸丙烯酸乙二醇酯(PDHAAGE).利用FT-IR、1H-NMR和GPC对所制备的单体和聚合物进行了表征,同时考察了单体转化率随聚合反应时间的变化.结果表明,聚合反应动力学曲线呈良好线性关系,表观聚合速率常数kp′为3.6 ×10-7 s-1;所得聚合物的分子量分布很窄.

| Abstract: | In this paper,dehydroabietic acid acrylic glycol ester(DHAAGE) was synthesized by the reaction of 2-hydroxyethyl acrylate with dehydroabietic acid chloride starting from dehydroabietic acid(DHA).Then poly(dehydroabietic acid acrylic glycol ester)(PDHAAGE) was prepared from the monomer DHAAGE,using atom transfer radical polymerization(ATRP) with ethyl 2-bromoisobutylate(EBr-iB) as an initiator and CuBr/2,2'-bipyridine as a catalytic system at 90oC.The resulting DHAAGE and PDHAAGE were characterized by FT-IR,... |
