The invention relates to low-viscosity, low-monomer aqueous polymer dispersions based on polychloroprene, and a process for the preparation thereof and the use thereof as a contact adhesive.

Low-viscosity aqueous adhesive polymer dispersions

The invention relates to a method for producing polymeric solids free of auxiliary emulators starting from polymer latices (dispersion), wherein a polymer dispersion with a starting ph-value greater than 9 is set to a ph-value of 6 to 9 by adding gaseous carbon dioxide and the polymer dispersion is subsequently coagulated by shearing and/or freezing.

Method for producing polymeric solids

Formulations based on anionically stabilized aqueous polymer dispersions, containing polychloroprene, to which carbon dioxide (CO) has been added, to a process for their preparation, to a device for increasing the carbon dioxide content of formulations based on anionically stabilized aqueous polymer dispersions, and to the use thereof in the production of adhesives, sealants, large-volume parts or coatings.
