RAFT: The ultimate polymer building technology

Together with the DuPont company, CSIRO has developed an innovative and world-class technology
known as RAFT (Reversible Addition-Fragmentation chain Transfer) which allows for the synthesis
of specifically crafted polymeric materials with enhanced properties and utility. The RAFT technology
allows for complete control over the size, shape and function of polymer molecules.
