General description

Need help choosing the correct RAFT Agent? Please consult the RAFT Agent to Monomer compatibility table.

Application

Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization
This is a RAFT agent for controlled radical polymerization, well-suited for methacrylates and methacrylamides. This is a more temperature stable alternative to Aldrich Prod No. 761257. Chain Transfer Agent (CTA)

Massimo Benaglia et al.
Journal of the American Chemical Society, 131(20), 6914-6915 (2009-05-01)
The polymerization of most monomers that are polymerizable by radical polymerization can be controlled by the reversible addition-fragmentation chain transfer (RAFT) process. However, it is usually required that the RAFT agent be selected according to the types of monomer being
