AQUEOUS EMULSION

摘要

The present invention relates to an aqueous emulsion comprising a dispersant of a modified polyvinyl alcohol with an ethylene unit content of 2 to 9 mol% and a degree of hydrolysis of at least 95 mol%, a dispersoid of a polymer of an ethylenically unsaturated monomer, and a ratio ( eta 2rpm/ eta 20rpm) of Brookfield viscosity at 30 DEG C, 2 rpm ( eta 2rpm) as against Brookfield viscosity at 30 DEG C, 20 rpm ( eta 20rpm) being 1 to 1.8 when the latter viscosity ( eta 20rpm) is adjusted to 5,000 to 10,000 mPa.S. The aqueous emulsion according to the present invention is excellent in structural viscosity (flowability, high speed application performance), provides coated layers with high water resistance and low-temperature stability, and can be suitably used extensively as an adhesive for paper, wood and plastics, as a binder for impregnated paper and non-woven products, as an additive for mortar, as a paint, and in paper and fiber processings.
