Anwendungen

L-Lactide upon polymerization gives poly(lactic acid), which finds many useful properties like biodegradable and nontoxic to the human body and the environment. Its polymer, poly-l-lactide is utilized in the repairing of orbital posterior floor fracture. Further, it is used as biomedical materials for tissue regeneration, matrices for drug delivery systems and alternatives for commercial polymeric materials to reduce the impact on the environment.

Bemerkungen

Moisture sensitive. Store in a cool place. Incompatible with oxidizing agents.
