The miscibility of poly(2‐hydroxyethyl methacrylate)/poly(styrene‐ co ‐acrylamide) (PHEMA/PSAm) blends was investigated by nonradiative energy transfer fluorescence spectroscopy using anthracene‐labeled PHEMA and carbazole‐labeled PSAm. The results show that the ratio of the carbazole and anthracene emission intensity, I c / I a , passes through a minimum at 47 to 57 mol‐% of acrylamide in PSAm copolymers in the blends, indicating that a ‘miscible window’ exists. It also was found that the results are consistent with those obtained by differential scanning calorimetry. The driving force for the miscibility of PHEMA/PSAm may be explained with a mean‐field theory.
