The phase behavior of binary mixtures of poly(acrylonitrile‐co‐methyl acrylate) (70 : 30) copolymer (B200) with various polymers including poly(N,N‐dimethyl acrylamide) (PNNDA), poly(maleic anhydride) (PMA), poly(vinyl pyrrolidone) (PVP), poly(2‐ethyl‐2‐oxazoline) (PEOX), poly(styrene‐co‐maleic anhydride) (50 : 50) copolymer (SMA), and poly(ϵ‐caprolactone) (PCL) was examined by differential scanning calorimetry (DSC). Miscibility of B200 with some of these polymers was observed over a limited range of composition. Several equations existing in the literature (Fox, Gordon—Taylor, and Kwei) have been employed to describe the dependence of glass transition temperature of the miscible blends as a function of the blend composition. In most cases a deviation from the weight‐average values of the experimental glass transition temperatures and of the values predicted by various equations was found. This has been attributed to specific interactions between the molecular constituents of the polymer pair.
