The variation of activity of components with concentration at different temperatures are used to find the equilibrium concentration, UCST, and LCST for the systems. Also by generalization of the method, Gel-Liquid equilibrium is studied in some three component systems: polymer-solvent-solvent.. UR - https://ijcce.ac.ir/article_10959.html L1 - ER -
