The first pair, PE/PIB, already has been examined by Flory, Eichin-ger, and Orwoll (15) to ascertain their possible mutual compatibility. 

It is not surprising that attempts have been made to derive equations of state along purely theoretical lines. This was done by Flory, Orwoll and Vrij (1964) using a lattice model, Simha and Somcynsky (1969) (hole model) and Sanchez and Lacombe (1976) (Ising fluid lattice model). These theories have a statistical-mechanical nature they all express the state parameters in a reduced dimensionless form. The reducing parameters contain the molecular characteristics of the system, but these have to be partly adapted in order to be in agreement with the experimental data. The final equations of state are accurate, but their usefulness is limited because of their mathematical complexity. 

Comprehensive tables of Flory-Huggins interaction parameters and their concentration and temperature dependences have been published, e.g. by Schuld and Wolf (1999) and by Orwoll and Arnold (1996).
