可聚合端羧基超支化聚胺酯的合成与表征

Synthesis and characterization of polymerisable carboxyl-terminated hyperbranched polyaminoester

以丙烯酸甲酯、二乙醇胺、三羟甲基丙烷、马来酸酐等为原料,通过3步合成反应合成了一种可聚合端羧基超支化聚胺酯。通过羟值和酸值监测反应进行的程度,确定其最佳合成条件为:反应温度为70℃,催化剂用量为1%,反应时间为3.5 h,并用红外光谱对产物结构进行表征。

A polymerisable carboxyl-terminated hyperbranched polyaminoester was synthesized with methylacrylate,diethanolamine,trimethylolpropane,maleic anhydride as raw materials.The extent of reaction was monitored by hydroxyl value and acid,the best conditions were as follows：the reaction temperature 70 ℃,catalyst amount 1%,the reaction time 3.5 h,the product was characterized by FTIR.
