摘要： A crepe process includes applying an adhesive composition to a nonwoven web, drying, and creping the nonwoven web on a creping drum. The improvement includes using an adhesive composition that includes an aqueous copolymer dispersion obtained by emulsion polymerization of a monomer mixture including 65 to 94.5% by weight of vinyl acetate, 5 to 30% by weight of ethylene, (meth)acrylamide, and 0.1 to 4% by weight of an N-methylol functional monomer. The N-methylol functional monomer constitutes from 25 to 85% by weight of the combined amounts of acrylamide and N-methylol functional monomer, which combined amounts constitute from 0.5 to 5% by weight of the monomer mixture. The emulsion polymerization is performed in the presence of 1 to 10% by weight of polyvinyl alcohol, based on the total weight of all monomers used for the polymerization. The adhesive composition does not include alkylphenol ethoxylates, phosphate ester surfactants, or sodium laureth sulfate.

摘要： This invention relates to an improved process for producing a vinyl alcohol containing polymer having a narrow particle size without substantial reactor fouling. The process for producing the vinyl alcohol containing polymer involves hydrolyzing a vinyl ester containing polymer, e.g., a polymer containing polymerized vinyl alkanoate units in the presence of an alcoholic medium and a hydrolysis catalyst in the presence of an alcoholic medium having finely divided, inert material such as an alkali metal carbonate dispersed therein. The finely divided inert material acts as nucleating sites for the polyvinyl alcohol as it precipitates from the solution during hydrolysis.
