Реферат: ABSTRACT Foam-backed pressure-sensitive adhesive tape having an open-cell polyurethane roam backing containing a foam-stabilizing fluoroaliphatic substance such as a fluoroaliphatic oligomer which affords repellency to oil and water. Moieties of the fluoroaliphatic substance similar to moieties of the polyurethane afford solubility in the polyurethane-forming mixture which is balanced against the insolubilizing effect of the carbon-bonded fluorine to concentrate the fluoroaliphatic substance at the cell membrane surfaces of the foam.
