    AnnotationFlow improvers are able to improve significantly flow properties of transported material. It was found that one class of efficient additives consists of copolymers and terpolymers synthesized by polymerization of long chain methacrylates with styrene and (meth)acrylic acid and styrene or 1-vinyl-2-pyrrolidone. For future development of better additives, the group contribution method represents a powerful tool; however the evaluation of particular group increments must be based on thermodynamic data on systems which are not hitherto available. In this work, liquid–vapor equilibria were determined ebulliometrically for several systems consisting of the above mentioned terpolymer + organic solvent at different temperatures and pressures.
