| Abstract: | Poly latic acid was prepared by melt-solid polycondensation through microwave.And it was characteriazed by element analysis,IR and NMR and thermal analysis,DSC and heat degradation.The results showod that this method can not only decrease the time of craftwork effectively but improve the molecular weight and nature of thermal process. |
