Abstract

We prepared a series of dendritic–linear block copolymers (DLBCPs) bearing a semirigid Percec-type dendron with ionophilic poly (ethylene glycol)(PEG) tails and a polystyrene (PS) linear polymer by nitroxide-mediated living radical polymerization (NMRP). As the DLBCPs are connected by an ester linkage, through hydrolysis the molecular weights of the DLBCPs were precisely characterized by gel permeation chromatography and MALDI-TOF MS. ...
