We report the results of theoretical and experimental studies of random amorphous styrene‐co‐vinyl phenol (STVPh) copolymer blends with ethylene‐co‐methyl acrylate (EMA). This work is a natural extension to our recently reported studies of the phase behavior of analogous STVPh blends with an homologous series of poly(n‐alkyl methacrylate) homopolymers, where we employed an association model together with parameters obtained from studies of miscible homopolymer blends. Here we emphasize that there is no conceptual difference between the average chemical repeat of a random copolymer and that of an analogous repeat unit of a homopolymer containing the same number and type of functional groups. The theoretically calculated miscibility maps for STVPh ‐ EMA copolymer blends are in outstanding agreement with experiment.
