RAFT Reagents

Reversible addition-fragmentation chain transfer polymerization (RAFT) is a novel and popular method to control the molecular weight and molecular weight distribution of radical polymerization. It allows the preparation of polymers with well-defined structures, including star, block, brush, comb, and gradient copolymers, as well as polymers with predictable functionality.

A commonly used reactive organic compound in a reversible addition-fragmentation polymerization process is a thiocarbonylthio group. Organic compounds containing this functional group are often referred to as RAFT agents. Currently, a large number of RAFT agents have been developed and synthesized on the market. Most of these compounds belong to one of five classes: dithioesters, xanthates, trithiocarbonates, dithiocarbamates, and dithiophosphonates. Raft is very broadly applicable to polymers, especially in the higher order functionality required fields of industrial, personal care, agricultural and biomedical polymers. These versatile, low odor and cost RAFT reagents are now available in gram to metric ton quantities.
