To extend PSRK model to describe polymer-solvent vapor-liquid equilibria (VLE)
the modified mixing rule for the parameter
b
is an exponent of 1/2 for the binary parameter
b
ij
. For pure polymers
a set of parameters (
a/MW
and
b/MW
) are employed to keep the parameters to be independent of molecular weight (MW). The PSRK model with modified mixing rule is applied to the prediction of VLE data for binary polymer solutions over a large rang of temperature and pressure with satisfactory results.
