Polymerization Control Reaction Of Trithiocarbonate

In recent years, the development of living polymerization has provided a powerful means for synthesizing polymers of various structures. Adding trithiocarbonate into the polymerization system can well control the polymerization reaction and can prepare polymers with special structures.

Trithiocarbonate is used for controlled free radical polymerization, especially suitable for chain transfer agents (CTA) for the polymerization of styrene, acrylate and acrylamide monomers. Trithiocarbonate has the structure of long alkane C12H25 and dimethyl acetic acid. It is widely used in the synthesis of biological materials in the body. It plays a role in controlling the molecular weight of the polymerization in the polymerization reaction. It has a wide range of applicable monomers and mild operating conditions. And the product molecular weight is more controllable.

Compared with dithiobenzoate RAFT chain transfer agents, trithioester RAFT polymerization is a very good way to functionalize the end of the polymer. By adjusting the ratio of trithioester RAFT reagent/initiator/monomer Proportion, you can get different degrees of polymerization.
