Abstract A series of tertiary amine-based hyperbranched poly(amine-ester)s have been synthesized by Michael addition polymerization of trifunctional monomer, TMEA and difunctional monomer, diacylates in chloroform, and the resultant polymers were subsequently treated with mercaptoethenol or 1-dodecanethiol for improving stability in storage. The caption efficiency of mercaptoethanol is much better than that of 1-dodecanthiol. Kinetic study reveals that the thiol group is consumed faster than the acrylate group when the polymerization with feed molar ratio of diacrylate/TMEA = 2/1 was carried out. At initial polymerization, monomer conversion increases fast, but the molecular weights increase slowly and sharp increase of the molecular weight occurs at the final polymerization. The hyperbranched polymers were well characterized by 1H NMR spectra and TD-SEC, and DBs of the polymers obtained are between 0.6 and 0.82, as well as the molar ratios of diacrylate/TMEA in the hyperbranched polymers are between 1.60 and 1.82. The fluorescence efficiency and quantum yields of HypET20, HypHT24 and HypDT24 has the following sequence: HypET20 > HypHT24 > HypDT24.

迈克尔加成聚合法合成和表征超支化聚（酯-胺）

摘要 通过三官能单体、TMEA 和双官能单体、二酰化物在氯仿中的迈克尔加成聚合反应合成了一系列叔胺基超支化聚（胺-酯），然后用巯基乙烯醇或 1-十二烷硫醇对所得聚合物进行处理。提高储存稳定性。巯基乙醇的标题效率远优于 1-十二烷硫醇。动力学研究表明，当二丙烯酸酯/TMEA = 2/1 的进料摩尔比进行聚合时，硫醇基团比丙烯酸酯基团消耗得更快。聚合初期，单体转化率增加较快，但分子量增加缓慢，最终聚合时分子量急剧增加。超支化聚合物的 1H NMR 光谱和 TD-SEC 得到了很好的表征，所得聚合物的 DB 介于 0.6 和 0.82 之间，超支化聚合物中二丙烯酸酯/TMEA 的摩尔比介于 1.60 和 1.82 之间。HypET20、HypHT24和HypDT24的荧光效率和量子产率顺序如下：HypET20>HypHT24>HypDT24。
