A universal efficient synthesis of cylindrical polymer brushes via CuAAC click chemistry using the grafting-onto method is presented. The backbones functionalized with azido units were obtained from post-modified poly(glycidol methacrylate)s (PGMA) given by controlled radical polymerization. The side chains had an alkyne terminal that was formed either by post-modification or in situ chain formation. The side chains includes poly(ethylene oxide), poly(epsilon-caprolactone), polystyrene, poly(meth)acrylates and polyacrylamides. The coupling reactions were conducted under a mild condition and an equivalent feed of alkyne to azido unit. The results indicated that the conversion of side chains during coupling reaction may reach around 90 %, even for PS105 of high molecular weight. Therefore, wormlike molecular brushes of various structures may be prepared very efficiently by present chemistry, which is also scalable.
