摘要： 对高聚物双流体配位模型状态方程进行了简化,忽略了其中的Q项,以简化的状态方程对4个纯高聚物(聚丙烯、聚苯乙烯、聚异丁烯和聚丁烯-1),2种纯溶剂(苯,环己烷)和2个高聚物/溶剂混合体系(聚异丁烯/苯和聚异丁烯/环己烷)进行关联,结果表明,简化的状态方程与原方程同样具有很好的关联精度和温度适用性．

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.
