Abstract
Thin porous moldings of silicone copolymers, suitable for use as membranes in separation processes, are prepared by forming a solution or suspension of silicone copolymer in two solvents L1 and L2, casting the suspension or solution, and removing solvent L1 to form a silicone copolymer rich phase A, effecting structure formation, and then removing solvent L2 and residues of solvent L2 to form a thin porous molding.
