Research Progress of Biodegradable Polymer Material Poly(lactic acid-glycolic acid)

Biodegradable material poly (lactic acid-glycolic acid, PLGA) has good biocompatibility and extensive application in the medicine fields such as drug delivery material, tissue engineering scaffold and surgical suture. The synthesis, properties and application of PLGA are reviewed in this paper, especially the research progress on the synthesis are introduced in detail. The future study of PLGA should be emphasized on reduce of the synthetic cost, and for this purpose the simple and practicable direct polycondensation method using lactic acid(LC) and glycolic acid(GA) as starting monomers should be paid more attention.
