Abstract: An aqueous composition includes polyvinyl alcohol, an acid having a pKa of at most 4.0, and a dispersion of a polymer in which vinyl acetate units constitute at least 60 wt % of the polymer. The polymer does not contain units of any N-methylol-containing monomer, and at least a portion of the polyvinyl alcohol is present in the form of an emulsion stabilizer for the polymer. The wet strength of a fibrous nonwoven substrate can be increased by applying one or more aqueous compositions that together include polyvinyl alcohol, an acid having a pKa of at most 4.0, and a dispersion of a polymer as described above, followed by a final drying step. A fibrous nonwoven article can be prepared in this way.

Abstract: Fluorochemical-free paper coatings which simultaneously exhibit good oil and grease resistance, hydrophobicity, and release properties are aqueous dispersions containing a water insoluble vinyl polymer, an addition-curable organopolysiloxane which cures through hydrosilylation, an Si—H functional crosslinker, and a catalyst for addition curing of the addition-curable organopolysiloxane. High oleophobicity, hydrophobicity, and release properties are developed even at low coating weights.
