    We studied the micelle formation of a diblock copolymer of styrene and ethylene oxide in mixtures of 2,6-dimethylpyridine (2,6-lutidine) and water. Micelles are formed in a broad solvent composition range with a volume fraction of water ranging from 0.05 to 0.85, where neither polystyrene nor polyethylene oxide homopolymers are soluble. The diffusion behavior of pure solvent mixtures and in solutions of copolymer micelles is reported.

    Studovali jsme tvorbu micel dvojblokového kopolymeru styrenu a ethylenoxidu ve směsích 2,6-dimethylpyridinu (2,6-lutidinu) a vody. Micely vznikaji v širokém rozmezí složení rozpouštědla s objemovym zlomkem vody 0.05 - 0.85, kde nejsou rozpustné ani homopolymery polystyrenu, ani ethylenoxidu. Bylo popsáno rovnež difuzní chování cistých rozpouštědlových složek ve studovaných micelárních roztocích.
