Abstract
Disclosed herein is a process for laminating a polar substrate with a film cast from a sulfonated block copolymer having at least one end block A and at least one interior block B wherein each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol percent sulfonic acid or sulfonate ester functional groups based on the number of monomer units. The film is exposed to water and dried onto a polar or active metal substrate. The laminates do not delaminate in the presence of water, or in a humidity of up to 85%, and at a temperature of at least 60° C. The laminates are used for a variety of applications including energy exchange applications.
