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

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.

Formulations based on anionically stabilised, aqueous polymer dispersions

Disclosed herein is a two-component polyurethane adhesive containing an isocyanate component a), an active hydrogen containing component which is stable against demixing b), optionally a catalyst for the reaction of a) with b) and optionally an auxiliary agent and an additive, characterized in that an active hydrogen containing component which is stable against demixing b) contains at least one hydroxyl group-containing low molecular weight chain lengthening agent having at least one C-C double bond or C-C triple bond and having a molecular weight of at least 86 and a functionality of at least 2 and containing no carboxyl groups.

Two-component polyurethane adhesives

Disclosed herein is an adhesive and a process for bonding with the adhesive containing an isocyanate prepolymer a), an isocyanate reactive component b) and a catalyst for the reaction of a) and b), characterized in that the catalyst comprises a compound corresponding to the following formula ##STR1## wherein R.sup.1 and R.sup.2 may be identical of different and denote an alkyl group having 1 to 4 carbon atoms,
