Abstract
The thermoseparation of aqueous solutions of Breox 50 A 1000, an ethylene oxide-propylene oxide 50:50 (w/w) random copolymer, was studied. The cloud-point diagram for Breox in water solution and the effects of electrolytes and surfactants on the cloud-point temperature (CPT) were determined. The Breox concentration in both phases after the thermoseparation was followed with a reversed-phase HPLC method. The effects of separation temperature and additives on phase composition were evaluated.
