Grafted ?comb-like? block copolymers based on hydroxyethylmethacrylate and ε-caprolactone, P(HEMA-co-HEMA-g-PCL)-b-PCL, were obtained through simultaneous ?grafting through? and ?grafting from? methods in a one-pot reaction by combining radical addition fragmentation transfer (RAFT) and ring opening polymerization (ROP). Copolymers were characterized by SEC, FTIR and TGA. Isothermal crystallization kinetics of a linear PCL and grafted copolymers were performed by DSC at different crystallization temperatures.
