Abstract
A method of synthesizing a polymeric membrane is described in which a polymer, for example a polyvinylidene polymer or a terpolymer of ethylene, chlortrifluoroethylene and an acrylic monomer is heated and blended with a solvent. The solvent may be a high boiling latent solvent, for example butyl benzyl phthalate or tri iso nonyl trimellitate. The heated blend is shaped, which may involve casting on a supporting material such as a braided tube. Subsequently, the blend is cooled to thereby induce polymeric membrane formation on the supporting material.
