Tóm tắt

Dendritic polymer based on polyester of trimetilolpropane and dimetilolpropanoic acid was synthesized via two methods. As compared to traditional method, reaction time of dendritic polymer under microwave support was shortened from 2 hr to 30 min. Their structures were determinated by FT-IR, NMR. Their molecular weights were determinated by mass spectroscopy (MS) and gel permeation chromatography (GPC). The obtained results showed that branching degree of the dendritic polyesters in generations were estimated over 75-95 percent.
