詳細

詳細

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.

アプリケーション

Drug Delivery including coating nanoparticles; end-group functionalization; macroinitiator or block precursor.

特徴および利点

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.
