Poly trimethylene carbonate ptmc
WebTrimethylene 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. WebNov 25, 2024 · Poly (trimethylene carbonate) (PTMC) can be prepared by ring-opening polymerization of 1,3-Trimethylene carbonate, which is an amorphous polycarbonate with a few crystals. At normal temperature, it is a flexible elastomer similar to that of rubber. The glass transition temperature is about −16 °C, elongation at break reaches up to 1250% .
