Simulations based on Cahn-Hilliard spinodal decomposition theory for phase separation in thermally quenched polymer/solvent/nonsolvent systems are presented. Two common membrane-forming systems are studied, cellulose acetate [CA]/ acetone/water, and poly(ethersulfone) [PES]/dimethylsulfoxide [DMSO]/

Light-scattering measurements and spinodal decomposition modeling have been used to quantify the kinetics of pore growth in thermally quenched polymersolvent-nonsolvent [poly(methyl methacrylate) (PMMA)/1-methyl-2-pyrrolidinone (NMP)/glycerin] solutions. Solutions of fixed composition were quenched
