|Abstract:||Phase behavior in polysulfone-carboxylated polysulfone (PSf-CPSf) blends was studied by glass transition observations in conjunction with enthalpy relaxation technique. Miscibility in all proportions was detected in blends where CPSf has a degree of carboxylation (DC, i.e. number of carboxyl groups per repeat unit) less than about 1·3. Partial miscibility was detected in blends for DC>1·4 and up to DC = 1·9, probably as a result of decreasing intermolecular interactions with increase in DC.|
