Polyurethane based tri-block copolymers namely poly(N-vinylpyrrolidone)-b-polyurethane-b-poly(N-vinylpyrrolidone) (PNVP-PU) and poly(dimethylaminoethylmethacrylate)-b-polyurethane-b-poly(dimethylaminoethylmethacrylate) (PDMAEMA-PU) were synthesized through atom transfer radical polymerization (ATRP) mechanism. The synthesized polymers were characterized(More)
The high molecular weight poly (ethylene oxide) was used to synthesize telechelic bromine terminated poly (ethylene oxide) polymers. The low molecular weight polystyrene anion was generated by living anionic polymerization by controlling monomer/initiator ratio. The living polystyrene anion was reacted with telechelic bromine terminated poly (ethylene(More)
