Ternary‐phase diagrams have been experimentally determined at 100°C for systems containing a series of poly( n ‐alkyl methacrylates), poly(ethylene oxide) (PEO), and a solvent [4‐ethyl phenol (EPh)]. A totally miscible phase diagram is experimentally determined for the poly(methyl methacrylate)/PEO/EPh system, while a closed‐loop diagram is observed for the analogous system containing poly(ethyl methacrylate). The corresponding phase diagrams of analogous mixtures containing poly( n ‐propyl methacrylate) or poly( n ‐butyl methacrylate) exhibit large heterogeneous areas. Theoretically predicted phase diagrams calculated using an association model developed in our laboratory are in general accord with these observations for ternary hydrogen‐bonded polymer/polymer solutions. © 1998 John Wiley & Sons, Inc.
