Thermodynamics of phase equilibria and critical phenomena of quasi-binary systems of multicomponent polymers 1 and 2 and of quasi-ternary systems consisting of multicomponent polymers 1 and 2 in a single solvent

Abstract

As an extension of our previous work, attempts were made to establish fundamental relations giving the spinodal curve (SC), the critical solution point (CSP), the cloud point curve (CPC) and the shadow curve for quasi-binary systems of multicomponent polymers 1 and 2 (P1/P2) and quasi-ternary systems consisting of multicomponent polymers 1 and 2 in a single solvent (P1/P2/S). The procedure of computer experiment based on the above fundamental equations derived was also attempted to be established. The systematic computer experiments were carried out to examine the effects of the molecular characteristics of polymers and the mutual interaction parameter on the phase diagram.
