Abstract: In the course of p-V-Tdata correlation by the equation of state(EOS's) on two-fluid coordination model for polymer solution.It was found that the term of Qin this EOS'Shas little influence on correlation calculation, because the Qwas dominated by hole fraction.Among polymer systems the hole fraction is much smaller than other cell fraction.So that theterm of Qcould be omitted in this EOS'Sand a simplified EOS'Swas obtained, a reducedform of this EOS's was presented and it was verified by four pure polymer systems[polypropylene, polystyrene, polyisobutylene, poly(betene-l)], two solvent systems (ben-zene, cyclohexane) and two polymer/solvent systems (polyisobutylene/benzene, poly-isobutylene/cyclohexane) that it has the same correlation accuracy as the initial EOS'Swith awide temperature range.
