Sammary: Various techniques of one‐step batch emulsion copolymerization of methyl methacrylate (MMA) or styrene (St) with N ‐vinylformamide (NVF) initiated by 2,2′‐azobis(2‐methylpropanamidine) (AIBA) or 2,2′‐azobis[4,5‐dihydroimidazol‐2‐yl] (AIP) dihydrochlorides in the presence of dextran, cetyltrimethylammonium bromide (CTAB) or without any stabilizers were examined to obtain monodisperse submicron and nano‐ particles, having both positive surface charge and hydrophilic surface. After hydrolysis in acidic media, the particle surface contained amino groups originating from NVF units along with carboxylic groups from hydrolyzed initiator residues. The obtained particles were tested as building blocks of hierarchic structures. Owing to their amphiphilic surface, the particles were capable of self‐assembling from their dispersions into three‐dimentional (3D) ordered arrays.
