One-step

artl ely us osite m eir un challenged from the points of new development of conventional polymers. Radical promoted cationic polymerization and trans-formation polymerization have been performed as ways to get block polymers [25–29]. the grafts with three different monomer units can modify the thermo-property and amphiphilic property of PVAc at a very wide range. This article reports a new ‘‘one-step’ ’ synthesis of a graft polymer, PVAc-g-[P(AN-r-BVE)-b-PCHO], based on radical/cationic transformation polymerization of a mixture of AN/BVE/CHO in the presence of PVAc-OH (Scheme 1). Furthermore, the graft polymer obtained is hydrolyzed to form a poly(vinyl alcohol)-based amphiphilic graft polymer and its aggregation behavior is also described. * Corresponding author.
