| 摘要 |
Highly filled crosslinkable emulsion polymer compositions containing vinyl aromatic monomers and acrylate or methacrylate monomers can be provided with improved retention of adhesive power in the face of attack by water and improved shelf-life by the presence of zinc ammonium carbonate in the composition. The zinc ammonium carbonate is preferably in the form of an aqueous solution prepared by reacting an equimolar amount of ammonium carbonate and ammonium hydrogen carbonate with zinc oxide and ammonia.
