主 题:continuous thermodynamics polymer solution polydispersity lattice model cloud-point curve shadow curve spinodal critical point
摘 要:using close-packed lattice models,a continuous thermodynamic framework is presented forphase-equilibrium calculations for binary solutions with a polydisperse polymer *** expressionfor the Helmholtz function of mixing is based on the revised Freed model developed *** parameter c_r and an energy parameter ε are used;the former can be temperature dependent,while the latter can depend on both temperature and chain-length of the *** discretemulticomponent approach is adopted to derive expressions for chemical potentials,spinodals and criti-cal *** continuous distribution function is then used in calculations of moments occurring inthose *** programs are established for cloud-point-curve,shadow-curve,spinodal and critical-point calculations for polymer solutions with standard distribution or arbitrarydistribution of *** the latter case,the derivative method developed previously is *** for phase-equilibrium calculations are
