Summary From theoretical considerations it is concluded that the demixing temperatures of moderately concentrated polymer solutions should manifest themselves in a change of the slope of the corresponding DSC trace; the effects are expected to suffice for detection by means of the commercially available dual furnace instrument DSC-2C from Perkin-Elmer. Measurements with 17 mg samples (10 wt.% poly(decyl methacrylate) in iso-octane, lower critical solution temperature) and with 40 mg samples (10 wt.% polystyrene in tert. butyl acetate, upper and lower critical solution temperature) corroborate the above considerations. Since the effects are rather small, special care must be taken to exclude artifacts.
