Description:
Poly(L-lactic acid) is a semi-crystalline polymer known for its strong optical activity and good mechanical properties. It is primarily used to synthesize biodegradable polymers for orthopedic devices, dental applications, as scaffolds for autologous skin grafts, wound dressings, and anastomosis systems. These materials are biodegradable because the polyester backbone degrades through simple hydrolysis, yielding non-toxic byproducts.
