Nanoaggregates were prepared from five samples of poly[(2-ethylhexyl acrylate)-ran-(tert-butylacrylate)]-block-poly(2-cinnamoyloxyethyl acrylate), P(EXA-tBA)-PCEA in block-selective solvents for P(EXA-tBA). The effect of varying diblock composition, block-selective solvent, and equilibrium temperature on thesize and shape of the nanoaggregates formed was investigated. Nanospheres were obtained after the photo-cross-linking of the spherical nanoaggregates. The tBA groups in the corona of these nanospheres could be hydrolyzedto give P(EXA-tBA-AA), where AA denotes acrylic acid, with a controlled fraction of AA units. Nanosphereswith low contents of AA groups in their corona disperse well in low-polarity solvents and bind effectively tostainless-steel surfaces.
