Description
General Description
Poly(DL-lactide) (PDLLA) is a synthetic biodegradable polymer prepared from the ring-opening polymerization of D,L-lactide. Unlike poly(L-lactide) (PLLA), which is semi-crystalline, PDLLA possesses an amorphous structure resulting from the random distribution of D- and L-lactide units along the polymer chain. This amorphous nature provides more uniform degradation behavior and improved processability for pharmaceutical and biomedical applications.
PDLLA undergoes hydrolytic degradation into lactic acid, a naturally occurring metabolite that is ultimately eliminated through normal metabolic pathways. Due to its excellent biocompatibility and tunable degradation profile, PDLLA has become one of the most widely utilized biodegradable polymers in drug delivery systems, tissue engineering scaffolds, absorbable implants, microspheres, nanoparticles, and medical devices.
Nanosoft Polymers offers PDLLA in a variety of molecular weights and functional end groups, including hydroxyl, carboxyl, amine, thiol, azide, biotin, maleimide, NHS ester, and PEG-based copolymers.
