ABSTRACT A method of preparing a porous membrane which includes the steps of dissolving a thermoplastic material which has both relatively non-crystalline and relatively crystalline portions into a solvent under conditions of temperature and time which cause the relatively non-crystalline portions of the thermoplastic to dissolve while at least a portion of the relatively crystalline portions of said thermoplastic material do not dissolve, but form a colloidal dispersion in said solvent. The colloidal dispersion and solvent are formed into a film, and thereafter precipitation of the dissolved thermoplastic portions is caused in the said film to form a porous membrane.
