摘要
以取代马来酸酐和二乙醇胺为原料,在常温下快速(2 h)合成了一系列的超支化聚酰胺-酯AB2单体,其结构经FT-IR表征。用中和滴定法跟踪测定反应体系的酸值,根据酸值与反应进度的关系,讨论了快速合成的意义。提出了可能的反应机理。
A series of AB2 type-hyperbranched poly（ amide ester） monomer were rapidly（2 h） synthesized from substituted maleic anhydride at normal temperature （ 28 ± 5 ）℃. The structures were confirmed by FT-IR. The relationships between acid numbers of the three different amidation reaction system, which were determined by tracking neutralization titration, and the degree of amidation reaction were studied. The feasibility to rapidly synthesize the AB2 monomer was also discussed. The possible reaction mechanism of amidation was suggested.
