Abstract: Aqueous polymer dispersions based on polychloroprene, a process for their preparation and their use in adhesive formulations. The aqueous polymer dispersion is obtained by a) preparing an aqueous polychloroprene dispersion with a gel content of 0.1 wt. %-30 wt. %, based on the polymer, prepared by polymerization at 0° C.-70° C. of chloroprene and, optionally, ethylenically unsaturated monomers which can be copolymerized with chloroprene and b) subsequently storing the dispersion at temperatures of from 50° C.-110° C. until the gel content has risen by at least 10 wt. % to 1-60 wt. %, based on the polymer.

Abstract: An aqueous polymer dispersion that includes a) a polyurethane dispersion having an average particle size of 60 to 350 nm and b) an aqueous silicon dioxide dispersion having a particle diameter of the SiO2 particles of 20 to 400 nm. The dispersion is prepared by mixing the polyurethane dispersion (a) with the silicon dioxide dispersion (b). The aqueous polymer dispersion can be used in adhesive compositions, which can be used to bond substrates together, especially substrates that are structural components of shoes.
