| 中文摘要 | a method has been developed to quantitatively determine the residual monomer in polylactide (pla) using thermogravimetric analysis (tga). the lactide monomer in pla is evaporated completely below the decomposition temperature of pla, thus the monomer content can be determined with a thermogram of pla. extensive experiments show that the residual monomer content is equal to the percent weight loss from 100 degrees c to 250 degrees c at a scanning rate of 10 degrees c/min. the measurement reliability has been evaluated by conducting parallel experiments and the results from tga are in good agreement with the test data obtained using hplc. the relative standard deviation (rsd) of the measurements is <8.0% at high contents (4.68%-10.33%), while rsd is <18% at a low level (0.3%), which indicates that the method is sufficiently precise for rapid determination of the residual monomer in pla.
