| Abstract: | Polyglycolic acid biodegradable polymers have good biocompatibility, and have extensive application in the medicine fields, such as drug delivery material, tissue engineering scaffold, and surgical suture. The synthesis, properties and application of different kinds of polyglycolic acid biodegradable polymers are introduced in this paper, especially the research progress of poly (lactic acid-glycolic acid) (PLGA) are reviewed in detail. The future study on polyglycolic acid biodegradable polymers should be emphasized on reducing their synthesis cost, and the simple and practicable direct polycondensation method using glycolic acid as starting monomer is noticeable. |
