FOVE model

The first equation-of-state theory developed for polymers was due to Flory, Orwoll and Vrij (1964) and Eichinger and Flory (1968), the so-called FOVE model. Each of the components is characterized by p, V and T obtained from data for the pure components. Two interaction terms, denoted Xj2 and Qi2, associated with the enthalpy and entropy of the mixture, are introduced. The equation of state is ... 

The FOVE model can predict negative mixing enthalpy and mixing volume as well as both LCST and UCST. The reorientation of segments arising from specific interaction is, however, ignored. The theory uses an entropy contact parameter, Q12, that counterbalances any effect that specific interaction has on the excess energy of the mixture.
