基本信息
| Linear Formula【线性分子式】 | H(C3H4O2)nOCH3 |
| NACRES | NA.23 |
| General description【一般描述】 | Poly (L-lactide) is a semi-crystalline polymer which exhibits strong optical rotation and good mechanical properties. It is mostly used in the synthesis of degradable polymers which are used in orthopaedic devices, in dental applications, as scaffolds for autografted new skin, wound covers, anastomose systems and stents. They are biodegradable since the polyester backbone degrades by simple hydrolysis to form non-toxic compounds. |
| Application【应用】 | Used in Drug Delivery including coating nanoparticles. Can be end-group functionalizated or used as a macroinitiator/block precursor. |
| Features and Benefits【特点和优势】 | High initial strength, good strength retention and high amount of crystallinity as much as 70% which in turn is responsible for the very slow degradation rate. |
