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&#xb0; C. The laminates are used for a variety of applications including energy exchange applications.

Sulfonated block copolymer laminates with polar or active metal substrates

Blends comprising a sulfonated block copolymer and particulate carbon are useful materials for membranes, films and coatings in applications which require high dimensional stability, high water vapor transport, high conductivity, and low flammability. The sulfonated block copolymer comprises at least two polymer end blocks A and at least one polymer interior block B wherein each A block contains essentially no sulfonic acid or sulfonate functional groups and each B block is a polymer block containing from about 10 to about 100 mol percent sulfonic acid or sulfonate functional groups based on the number of monomer units of the B block.

Blends of sulfonated block copolymers and particulate carbon and membranes, films, and coatings comprising them

The current invention concerns a textile coating composition comprising an aqueous emulsion of a midblock sulfonated styrenic block copolymer and a poly(vinyl alcohol). It also concerns a method for preparing the textile coating composition and its application. It also concerns fabrics on which the coating compositions have been applied.

Textile coating composition

A rotary enthalpy exchange wheel having a rotatable wheel with air passageways extending from a front side to a back side for passing air streams therethrough. The wheel has a rigid substrate which is coated or laminated with a desiccant composition having a sulfonated block copolymer. The sulfonated block copolymer has 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.
