[0002] Poly (L-lactic acid) is an important biodegradable polymer material. It is non-toxic, non-irritating, biodegradable and absorbable, high in strength, good in plasticity, and easy to process. The degradation cycle is 2 to 12 months. The degradation cycle can also be changed according to the addition of different modifiers. Poly (L-lactic acid) is enzymatically decomposed in the body and eventually forms carbon dioxide and water, which has good biocompatibility. Poly (L-lactic acid) has many uses, mainly in surgical sutures, dentistry, ophthalmology, pharmaceutical controlled release systems, artificial skin, artificial blood vessels, bone and soft tissue defect fillers, bioabsorbable stents and other medical fields. In the synthesis process of poly (L-lactic acid), the product sedimentation process is involved.
