Abstract
We prepared polyhydroxybutyrate and poly(hydroxybutyrate-co-hydroxyval erate) porous membranes with phase inversion method from ternary syste m and different percentages of three different non-solvents (NS): tetr ahydrofuran, dimethylformamide and ethanol. Retention factor (% R), wa ter and ethanol fluxes are given. The maximum value of % R for 8-10% N S is correlated viith the initial collodion ternary phase diagram.
