Poly(trimethylene carbonate-co-D,L-lactide), 50:50, IV 1.1 dL/g

Poly(trimethylene carbonate-co-L-lactide) (PTMCLLA) is a biodegradable copolymer that has gained popularity in various biomedical applications, including drug delivery, tissue engineering, and wound healing. This copolymer combines the unique properties of both monomers, resulting in a material with improved rigidity, increased biodegradability, and varied degradation compared to the homopolymers.

The biodegradation rate of PTMCLLA is typically greater compared to PTMC homopolymer due to the additional sites susceptible to hydrolytic degradation. The degradation rate of PTMCLLA is also influenced by other factors such as the molecular weight, crystallinity, pH, temperature, and presence of enzymes.
