- Abstract
- Expanding upon a previous study, the modified double lattice model for mixed-solvent polymer systems was developed by employing new universal constants. The calculated results of the proposed model showed good agreement with Monte Carlo simulation results and hypothetically predicted Types 0 and 3 phase separations of the Treybal classification. To describe real systems, the chain length of the polymer and energy parameters were adjusted to fit experimental data. The proposed model correlated well with experimental data from real systems incorporating low to high molecular weight polymers (PEO 200, dextran 40 350, PS 300 000) using reasonable model parameters.
