Grafting-through strategy

The grafting through strategy means the preparation of cylindrical brushes by the polymerization of preformed MMs. This was the first method in the synthesis of cylindrical brushes. For the first time, Tsukahara et al. [108] successfully obtained cylindrical brushes by the radical polymerization of MMs. Short polymer chains with a polymerizable vinyl chain end were first made by anionic polymerization and sequential end-functionalization. Further radical polymerizations of the premade MMs yielded cylindrical brushes with uniform side chains. This method was then further employed by Schmidt et al. [109, 119-121] and Ishizu et al. [122-127] to...
