Liquid-liquid equilibria for solutions of polydisperse polymers. Continuous thermodynamics for the close-packed lattice model

Effect of Chain‐Length Dependence of Interaction Parameter on Spinodals for Polydisperse Polymer Blends

“…Therefore, polydispersity has a strong influence on the phase behavior of polymer systems. During the last few decades, various theoretical approaches have been developed to investigate the phase behavior of polydisperse polymer systems 2–10. In 1970, Koningsveld et al11 first dealt with the thermodynamics and phase behavior of quasibinary systems using the Flory‐Huggins (FH) lattice theory,2 by treating the system as a multicomponent one.…”

Participation of molecular simulation in the development of molecular-thermodynamic models

“…The expression has further been used to develop a double lattice model to account for oriented interactions from hydrogen bonding, which has been successfully used for describing liquid-liquid equilibria for systems having UCST, LCST, loop type and sand clock type coexistence curves. The double lattice model has been further extended to continuous thermodynamics for systems containing very many components [51][52][53].…”

Critical properties of polydisperse fluid mixtures from an equation of state

“…Nezebeda et al [9][10][11][12][13][14] For spinodals and critical points, we need stability criteria. For lattice models or their modifications, the stability criteria were successfully established for systems containing continuous components [18][19][20][21][22]. However, for equations of state, we remain at a beginning stage.…”
