Factors Affecting PLA Degradation

The degradation of polymers occurs mainly as a result of attack by external elements. This is because polymer chains are highly stable and seldom undergo autocatalysis. Although 

Biodegradables Polymers that can be broken down through 

Bioresorbables Polymers that can be fully eliminated from the body. These polymer implants undergo bulk degradation and are resorbed in vivo and then naturally metabolized. Such bioresorbable polymers do not cause side effects 

Bioerodibles Similar to bioresorbables. However, with these polymers the focus is on surface breakdown in vivo
