Trimethylene carbonate is the monomer of PTMC. It is mainly used to synthesizes PTMC and other copolymers, such as PTMC-LA. There are widely used in the surgical suture, drug controlled release material and other application.

Trimethylene carbonate is easy to homopolymerize and copolymerize, and the initiator has a wide selection range. It can be used as anionic, cationic, and coordination initiators for ring-opening polymerization. In addition, enzymes can also be used to initiate polymerization.

The use of cationic initiators is prone to decarboxylation due to the transition state of cationic ions. As a result, ether bonds are introduced into the main chain of the polymer. Among all polymerization systems, coordination polymerization is ideal, and high-yield, high-molecular-weight polymers can be obtained.


Trimethylene carbonate is a versatile material used in various industries. One of its main applications is in the field of biomedical engineering, where it is used to produce biodegradable polymers. These polymers are commonly used for the fabrication of medical implants, drug delivery systems, scaffolds for tissue engineering, and other medical devices.

Trimethylene carbonate is a chemical compound that is a cyclic carbonate. It is a colorless and odorless solid at room temperature. It has a molecular formula of C4H6O3 and a molecular weight of 102.09 g/mol. 

Trimethylene carbonate is highly reactive and has a low melting point, making it useful for various applications in polymer chemistry. 

Trimethylene carbonate is not inherently toxic. However, like any chemical substance, it can be toxic if used or handled improperly. 

The solubility of Trimethylene carbonate is moderate, meaning it is not completely soluble in water or other polar solvents. However, it can be dissolved in organic solvents such as chloroform, dichloromethane, and tetrahydrofuran.

Some of the advantages of using trimethylene carbonate as a monomer are:

  • It can be synthesized from renewable resources, such as glycerol and carbon dioxide.
  • It can produce biodegradable polymers with biomedical applications, such as poly(trimethylene carbonate) (PTMC) and its copolymers.
  • It can be used to modify the properties of other polymers, such as poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG), by copolymerization or blending.
  • It has a positive temperature coefficient (PTC) effect, which means its electrical resistivity increases with temperature. This makes it suitable for temperature-sensitive devices, such as current protection and microswitch sensors.
