Hema raft polymerization

RAFT polymerization has been used to synthesize a wide range of polymers with controlled molecular weight and low polydispersities (between 1.05 and 1.4 for many monomers). RAFT polymerization is known for its compatibility with a wide range of monomers as compared to other controlled radical polymerizations. Some monomers capable of polymerizing by RAFT include styrenes, acrylates, acrylamides, and many vinyl monomers. Additionally, the RAFT process all… WebDavid Pownall is an academic researcher from University of Bradford.
