140. Müller, A.H.E.; Cheng, G.; Böker, A.; Krausch, G.: Unimolecular amphipolar nanocylinders via a 'grafting from' process using ATRP, Polym. Mater. Sci. Eng. 84, 91 (2001)
Core-shell cylindrical polymer brushes were synthesized by a "grafting from" procedure using Atom Transfer Radical Polymn. (ATRP) from functionalized poly(2-hydroxyethyl methacrylate). We obtained well-defined brushes with polystyrene (PS), poly(tert-Bu acrylate) (PtBA), PS-b-PtBA, or PtBA-b-PS as side chains. AFM of these brushes on silicon and mica surfaces reveals unique structural patterns. The hydrolysis of the PtBA blocks of brushes with diblock side chains afforded amphipolar brushes, serving as unimol. micelles. These polymers show interesting structural response to solvent quality.
