“…[19][20][21] and to derive the equations of SP and CSP for multicomponent polymer 1 /muhicomponent polymer 2 /single solvent (quasiternary system) (refs. 19,22) systems in the manner that the thermodynamic requirements are strictly satisfied, and to examine the effect of the molecular weight distributions (MWD), the average DP of the two original polymers in the above systems on phase diagram. Here, in the framework of the modified Flory-Huggins polymer solution theory, we take into consideration the concentration dependence of the thermodynamic interaction parameter x12 between polymer 1 and polymer 2 for quasi-binary system.…”

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 (P l/P2) and quasiternary systems consisting of multicornponent polymers 1 and 2 in a single solvent (PI/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.

Theoretical equations and a calculation method giving cloud point curve (CPC) for a multicomponent polymer 1/multicomponent polymer 2/single solvent system (i.e. quasi‐ternary system) were derived on the basis of the Flory‐Huggins solution theory. The systematic calculations based on this method were carried out to examine the effects on CPC of the type of molecular weight distribution, the polydispersity and the weight‐average degree of polymerisation of the two original polymers, and three thermodynamic interaction parameters between solvent‐polymer 1 (X01), solvent‐polymer 2 (X02) and polymer 1‐polymer 2 (X12). The shape of CPC sensitively depends on the polydispersity of the original polymer and, with an increase in polydispersity, the immiscibility region becomes wider.
