Patent ID: 8519047

Claim:
An aqueous polymer dispersion, 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 of chloroprene in an aqueous emulsion at 10° C.-25° C. and at pH value of 10-14 and, optionally, ethylenically unsaturated monomers which can be copolymerized with chloroprene and b) subsequently conditioning 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, wherein the aqueous polymer dispersion has a gel content of between 1-60 wt. % based on the polymer and a pH value of between 10-14 and wherein the aqueous dispersion does not have a significant drop in pH after storage for 7 days at 60° C.
