Poly (trimethylene carbonate) is a polymer used in biomedical applications. The polymer is often abbreviated PTC or PTMC. It has a melting point between 45 degrees and 48 degrees Celsius and a white, crystalline appearance.

It is produced by heating trimethylene carbonate, converting the colorless solid into an aliphatic polycarbonate. It can also be copolymerized with different lactone monomers to create materials with specific chemical and physical properties. The biodegradable polymer is frequently combined with materials in the hydrophilic groups, such as poly (ethylene glycol).

PTMC remains an effective choice for bone regeneration due to the high flexibility of the material. PTC is highly elastic and degrades by surface erosion within about 12 weeks. It produces no acidic degradation byproducts, limiting the risk of inflammatory tissue reactions compared to collagen membranes.

Many studies have evaluated PTC against other materials for absorbable sutures, comparing knot security, tensile strength, suture absorption, and inflammatory reactions. Various clinical studies have found that PTC performed better compared to other absorbable sutures such as chromic catgut, polydioxanone, and polyglactin 910.
