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.


No, PTMC (PolytetraMethylene Carbonate) is not inherently hydrophobic. Its hydrophobicity can vary depending on the specific structural properties and modifications of the polymer.

Poly trimethylene carbonate is a biocompatible and biodegradable polyester, which is a type of polymer. It is synthesized from trimethylene glycol and carbon dioxide through a polymerization process.

Poly trimethylene carbonate (PTMC) is a biodegradable polymer that has various applications in the field of medicine. It can be used in the production of drug delivery systems, such as nanoparticles, micelles, and implants.

Additionally, PTMC can be used as a scaffold material for tissue engineering and regenerative medicine, as it can support cell growth and tissue regeneration.

Poly trimethylene carbonate (PTMC) is generally considered to have low toxicity. It is biocompatible and has been extensively studied for various medical applications.
