AN AQUEOUS -SOLVENT BASED PROCESS FOR CONTINUOUS MANUFACTURING OF SUPPORTED ION SELECTIVE MEMBRANES

A membrane, for example an ion exchange membrane, is made by preparing a curable liquid using at least one aqueous solvent. The curable liquid is continuously cast onto a substrate to form a membrane precursor. The membrane precursor is continuously cured to form a membrane. Optionally, the curable...

More Information
Summary:A membrane, for example an ion exchange membrane, is made by preparing a curable liquid using at least one aqueous solvent. The curable liquid is continuously cast onto a substrate to form a membrane precursor. The membrane precursor is continuously cured to form a membrane. Optionally, the curable liquid may be made by mixing a water soluble aliphatic sulfonic acid monomer with a pair of crosslinking monomers and a water soluble free-radical generating catalyst. Optionally, the method may include one or more steps of processing the membrane.
