    Abstract: Adhesives comprising polyvinyl ether copolymers having a weight-average molecular weight > 10,000, which are composed of a) from 0 to 95% by weight of vinyl ethers of the formula I H2C = CH-O-R, b) from 5 to 100% by weight of hydrophilic vinyl ethers of the formula II H2C = CH-O-R , and c) from 0 to 30% by weight of further monomers, in which R is a C1-C10-alkyl group and R1 is an aliphatic or cycloaliphatic radical which may be substituted by hydroxyl groups or interrupted by nonadjacent groups -Y-, where Y is an oxygen atom, a sulphur atom, a group NR or N R R X , in which R and R independently of one another are a hydrogen atom or a C1-C4-alkyl group, and X is a counteranion, and the molar ratio of carbon atoms to the sum of groups Y and hydroxyl groups in the aliphatic or cycloaliphatic radical is from 1.01:1 to 6.5:1.

    Abstract: An aqueous polymer dispersion having a solids volume concentration of 50% by volume or more, obtained by free-radical aqueous emulsion polymerisation of free-radical-polymerisable monomers other than vinyl and vinylidine halides, with addition of an aqueous starting polymer dispersion having a certain diameter distribution of the starting polymer particles present therein, by the feed process.
