The apparatus for total pressure measurement in polymer + solvent systems has been designed recently. In the presented work, the range of functioning of this apparatus was extended to allow investigations at higher temperatures. A direct capacitance pressure sensor (Baratron) was replaced by a pressure transducer, which may be heated up to 200 oC. In addition, the solutions with higher concentrations of polymer can be studied in contrast to the ebulliometric method, which is limited because of problems with physical boiling of viscous mixtures.
