Poly trimethylene carbonate
Did you know?
Poly(trimethylene carbonate) (PTMC) is an aliphatic polycarbonate synthesized from the 6-membered cyclic carbonate, trimethylene carbonate (1,3-propylene carbonate or 1,3-Dioxan-2-one). Trimethylene carbonate (TMC) is a colorless crystalline solid with melting point ranging between 45°C and 48 °C and boiling … See more In opposition to five-membered cyclic carbonate, the six-membered ones like trimethylene carbonate are thermodynamically less stable than its polymer, undergoing the ring-opening polymerization with … See more PTMC is a predominantly amorphous polymer in the relaxed state but it can present some crystallinity, particularly when the chains are … See more Due to the predominant amorphous nature, PTMC is a flexible polymer with rubbery behavior. In addition, the biodegradability and biocompatibility of PTMC make it to … See more http://www.polymtek.com/index.php?id=1461
