Abstract

Covalent modification of poly(alkylene oxides), block copolymers of ethylene oxide and propylene oxide with M ∼ 2000, with fluororescein isothiocyanate or 7-nitrobenzo-2-oxadiazole taken in a ratio of 0.6–1.0 mol of label/mole of polymer leads to changes in the physical state of polymers and their solubility in water decreases, as well as the partition coefficient in the hexane-water system and the critical concentration of aggregation and dimensions of the formed particles.
