Abstract
Poly-D.L-lactide (PLA) homopolymer has been prepared by anionic ring-openin g polymerization of D.L-lactide by potassium poly(ethylene glycol-200)ate. The influenced factors of polymerization such as the amount of the initiato r, reaction period and temperature, concentration of Th monomer, feed way o f the reaction mixture have been investigated. PLA with viscosity-average m olecular weight of 5.5x10(4) has been obtained. The homopolymers are charac terized by GPC, DSC, IR and (HNMR)-H-1.
