| Abstract: | Poly(L-lactic acid)(PLLA)was successfully obtained by the melt/solid polycondensation of L-lactic acid.The effects of some factors,such as various catalysts,reaction temperature,reaction time and the size of preformed polymer particles,on the reaction velocity of solid state polycondensation were discussed.The results show that it was favourable to control molecular weight of the resulting polymer by using the vacuum drying oven under appropriate reaction conditions. |
