Paper Title:
Study on the Synthesis and Characterization of Polylactic Acid/Maleic Anhydride Copolymer
  Abstract

Hydroxyl terminated lactic acid prepolymer was synthesized with poly ethylene glycol (PEG).The malaya acid anhydride modified PLA by fuse polymerization, and the different technological conditions (temperature, reaction time and so on) were discussed by the orthogonal design approach. The result of the orthogonal test indicated that, the product molecular weight had enhanced greatly with the Malaya acid anhydride and the PLEG mass ratio 1:15, at 130°C for 15h. The products were characterized by DSC, IR and SEM, Mechanics performance and water affinity performance of the products was determined, and the degradation behavior in vitro simulated bioenvironmental condition was studied. Mechanics performance was improved, and the good water affinity performance biodegradability was maintained.
