Collection: Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization Reagents

Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization Reagents — includes thiocarbonylthio compounds such as dithioester and trithiocarbonate derivatives, for example N-Succinimidyl 4-Cyano-4-(phenylcarbonothioylthio)pentanoate and 2,2'-[Thiocarbonylbis(sulfanediyl)]bis(2-methylpropanoic Acid). This class functions as a chain transfer agent in the RAFT type of controlled radical polymerization mechanism.

RAFT Polymerization Reagents are used by polymer chemists to control chain growth and molecular weight distribution in radical polymerization, producing polymers with more defined architectures such as block or gradient structures. Compounds with an N-succinimidyl group such as N-Succinimidyl 2-(Dodecylthiocarbonothioylthio)-2-methylpropionate facilitate conjugation of polymer chain ends with biomolecules, while Tetraethylthiuram Disulfide and Tetrahydrofuran-2-yl Pyrrolidine-1-carbodithioate are used as control agents in certain polymerization systems.

Selection of a RAFT agent should be adjusted to the type of monomer being polymerized, the desired end-chain functional group for further modification, and the thermal stability of the reagent during the polymerization process. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
