Thiocarbonylthio RAFT agents synthesis

The synthesis of block copolymers based on polymers formed by other mechanisms can be made by first preparing an end functional pre-polymer which is converted to a polymer with thiocarbonylthio groups by end group transformation. This is then used as a macro-RAFT agent in preparation of the desired block copolymer (Scheme 6.11). We first exploited this methodology to prepare poly(ethylene oxide)-Z>/ock-poly(St) from commercially available hydroxy end-functional poly(ethylene oxide)." ...
