M. Banaszak et al., COPOLYMER SAFT EQUATION OF STATE - THERMODYNAMIC PERTURBATION-THEORY EXTENDED TO HETEROBONDED CHAINS, Macromolecules, 29(20), 1996, pp. 6481-6486
Thermodynamic perturbation theory of the first order (TPT1) is extende
d to heterobonded chains, such as heteronuclear and branched copolymer
s. The TPT1 formalism provides the basis for a copolymer equation of s
tate. This new copolymer equation of state, referred to as Copolymer S
AFT (Statistical Associating Fluid Theory), explicitly accounts for th
e effects of chain heterogeneity and microstructure. In order to illus
trate potential future applications, Copolymer SAFT is used to calcula
te high-pressure cloud points in real polymer solutions of supercritic
al propane + poly(ethylene-co-butene).
