| Abstract: | This review focused on the recent research progress in the modification of poly(lactic acid).The modification methods included direct polycondensation method,ring-opening polymerization,and chain-extending method.The molecular weight of poly(lactic acid) copolymers obtained by ring-opening polymerization was higher than that by direct polycondensation method.The chain-extending method could be used together with others.The application of modified poly(lactic acid) was reviewed,particularly in medical and pa... |
