摘要：
The liquid-liquid equilibrium (LLE) calculation for polymer solutions is essential for processes design of polymerization. The hydrogen bonding in polymer solutions leads to deviate remarkably from normal solutions behaviors. The perturbed hard-sphere-chain-association (PHSC-AS) equation of state (EoS) is applied to calculate the liquid-liquid equilibrium (LLE) of polymer mixtures with hydrogen bonding association such as self-and cross-association with various phase behaviors such as UCST, LCST and closed-loop of polymer solutions. In addition, the calculation results are compared with those obtained by the PC-SAFT EoS, which is known to be useful for calculating phase equilibria of polymer systems. PHSC-AS EoS shows a satisfactory performance for LLE calculation with similar accuracy compared to that with PC-SAFT EoS. (C) 2017 Elsevier Ltd. All rights reserved.
