Trimethylene carbonate

Trimethylene carbonate, or 1,3-propylene carbonate, is a 6-membered cyclic carbonate ester. It is a colourless solid that upon heating or catalytic ring-opening[1] converts to poly(trimethylene carbonate) (PTMC). Such polymers are called aliphatic polycarbonates and are of interest for potential biomedical applications. An isomeric derivative is propylene carbonate, a colourless liquid that does not spontaneously polymerize.

Preparation

This compound may be prepared from 1,3-propanediol and ethyl chloroformate (a phosgene substitute), or from oxetane and carbon dioxide with an appropriate catalyst:[2]

HOC3H6OH + ClCO2C2H5 → C3H6O2CO + C2H5OH + HCl
C3H6O + CO2 → C3H6O2CO

This cyclic carbonate undergoes ring-opening polymerization to give poly(trimethylene carbonate), abbreviated PTMC.[2]

Medical devices

The polymer PTC is of commercial interest as a biodegradable polymer with biomedical applications.[3] A block copolymer of glycolic acid and trimethylene carbonate (TMC) is the material of the Maxon suture, a monofilament resorbable suture which was introduced in the mid-1980s.[4] The same material is used in other resorbable medical devices.[5][6][7][8]
