ABSTRACT:
A method of shaping an organic polymer insoluble in a polar solvent comprises reacting an insoluble organic polymer containing at least one Lewis acidic electron attracting group or Lewis basic group with a sufficient amount of a lower alkylene oxide to alkoxylate the Lewis group and form an alkoxylated product soluble or easily dispersible in a polar solvent, dissolving or dispersing the alkoxylated product in a polar solvent, shaping the alkoxylated product into the desired form by applying the solution or dispersion to a support and removing the polar solvent, and hydrolyzing the alkoxylated product to obtain the original polymer in the desired form. Products made by this process include self-supporting polymeric films and porous diaphragms for electrolytic cells made by impregnating suitable porous supports with the alkoxylated product.
