Abstract
Abstract Polymer composition, useful as or in binders, coatings or adhesives, comprises (A) carboxylic acid copolymer emulsion and (B) halohydroxypropyl- and/or glycidyl-ammonium salt polymer wherein the polymer molecules are sufficiently swollen as to readily react with and penetrate interstices amongst emulsion (A) on drying the mixture. Coatings, binders or adhesives employing the composition are activated by base for coating or impregnating substrates, particularly non-woven fabric or fabric laminate, whereupon on drying and curing the mixture the polymer becomes crosslinked and insoluble.
