Souhrn Dizertační Práce Summary of the PhD Thesis SUMMARY OF THE PH.D. THESIS In the presented work, two different approaches for the formation of new functional nanoassemblies in aqueous solution were investigated. AB- and ABC-type of stimuli-responsive block co- and terpolymers and, eventually, additives like cadmium containing salt or boron clusters were utilized in the self- and/or co- assembly processes. In the self-assembly approach diblock copolymer polystyrene-block-poly((sulfamate- carboxylate)isoprene), (PS-PISC), and triblock terpolymer poly((sulfamate-carboxylate)isoprene)-block- polystyrene-block-poly(ethylene oxide), (PISC-PS-PEO), were synthesized by living anionic polymerization and functionalized via post polymerization reaction with chlorosulfonyl isocyanate. (Samples of block copolymers were synthesized by G. Mountrichas and S. Pispas from the Theoretical and Physical Chemistry Institute, National Hellenic Research Foundation, Athens, Greece). As a result, highly incompatible block copolymers, consisting of polyelectrolyte block with pH sensitive and insensitive group at the same monomeric units and some unmodified double bonds were achieved. The structures of self-assembled PS- PISC and PISC-PS-PEO nanoparticles in aqueous solutions were studied in the pH range from 1 to 10 by a...
