Aqueous polymer dispersion, its preparation and use

Abstract

The present invention relates to aqueous dispersions preparable by polymerization of an olefinically unsaturated, water-insoluble compound in the presence of a water-soluble allyl or vinyl ether of the formula 1 in which b is 0 or 1 n is 0 or 1 k is an integer from 1 to 20, X is O or N[(A—O)m—R] A is C2-C4-alkylene m is an integer from 5 to 900, and R is H or C1-C4-alkyl, and in which A is not exclusively C3- or C4-alkylene, by mixing the olefinically unsaturated water-insoluble compound with the water-soluble allyl and vinyl ether in water, and triggering the polymerization by a free-radical initiator.
