Abstract

An extension of the statistical associating fluid theory to describe branched chainlike molecules is presented. The so-called SAFT-Branched (SAFT-B) equation of state is based on Wertheim's first- and second-order thermodynamic perturbation theory for chain fluids. The branched chains are described at the first-order perturbation level and the articulation points are considered using the second-order perturbation approach.
