Beschreibung
Zusammenfassung:	High performance filters comprising a basestock impregnated with an aqueous based poly(vinyl alcohol) graft emulsion copolymer as binder. The aqueous based poly(vinyl alcohol) graft emulsion copolymer binder is prepared by graft polymerizing one or more ethylenically unsaturated monomer in an aqueous poly(vinyl alcohol) solution in which at least 30 % of the total poly(vinyl alcohol) is 70 to 97 mol % hydrolyzed.
