PTMC

PTMC (poly(trimethylene carbonate)) is a biodegradable aliphatic polyester commonly synthesized through ring-opening polymerization of trimethylene carbonate monomers. It is valued in the biomedical and pharmaceutical sectors as a flexible, elastomeric polymer that degrades through hydrolysis into non-toxic metabolites, making it suitable for temporary implants and drug delivery systems where material resorption is desirable. Engineers select PTMC over conventional non-degradable polymers when tissue integration and eventual elimination of the device are critical design goals, particularly in soft-tissue applications where mechanical compliance is needed during the healing period.
