in this work, the aqueous two-phase formation characteristics of PEG, poly (propylene glycol) (PPG) and poly (ethylene glycol dimethyl ether) (PEGDME) with a number of electrolytes containing NaCl, KCl, MgCl2, NH4Cl, NaNO3, NaCO3, Na3Cit, (CH3)4NCl and Na2CO3 been studied systematically and Phase diagrams have been determined for these systems at 298.15, 308.15 and 318.15 K. the effect of temperature, type polymer, polymer molar mass, size and charge of the cation and anion of electrolyte on phase forming abilities of the investigated polymer-salt aqueous two-phase systems were studied.
