摘要：
This paper has shown that the melt polycondensation of LA can be achieved efficiently under microwave irradiation and the reaction time can be shortened considerably compared with conventional heating. The polycondensation was successfully conducted with SnCl2 activated by TSA. At the optimal amount of catalysts, namely 0.45 wt% SnCl2 and equal mol ratio of TSA, PLLA with theMv of 5.08×104 g/mol was obtained at 528 W for 40 min.
