4-Cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl]pentanoic acid

The supply of low cost, high purity and effective Reversible addition−fragmentation chain-transfer (RAFT) Agents is the essential element in the industrial implementation of RAFT polymerization technology.

A series of polymerization were carried out using RAFT agents and monomers yielding well-defined polymers with narrow molecular weight distributions. The process allows radical-initiated growing polymer chains to degeneratively transfer reactivity from one to another through the use of key functional groups (dithioesters, trithiocarbonates, xanthates and dithiocarbamates). RAFT agents help to minimize out-of-control growth and prevent unwanted termination events from occurring, effectively controlling polymer properties like molecular weight and polydispersity. RAFT agents are commercially available. RAFT does not use any cytotoxic heavy metal components (unlike ATRP).

RAFT (Reversible Addition Fragmentation chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

Over the past two decades, the rapid advance of controlled living polymerization (CLP) techniques.
