FLEXIBLE WATER ABSORBENT POLYMER COATING

摘要

The present invention provides a liquid water-swellable coating compound, which is substantially devoid of volatile non-reactives. The water-swellable coating compound can be applied, to an article and cross-linked in place on the article to create a water-swellable, super absorbent polymer coating. The super absorbent polymer coating of the present invention is a flexible water-absorbent coating and comprises a cross-linked polymer prepared by polymerizing a reactive mixture, which comprises: substantially between thirty-five weight percent (35%) and ninety-nine and nine-tenths weight percent (99.9%) of one or more amine neutralized monomer; substantially between one tenth of one weight percent (0.1%) and fifteen weight percent (15%) cross-linking monomer; substantially between zero weight percent (0%) and fifty weight percent (50%) water soluble, substantially monofunctional oligomer; and substantially between one-half of one weight percent (0.5%) and five weight percent (5%) of an appropriate cross-linking agent.
