Abstract
The invention relates to a method for producing metal salt nanogel-containing aqueous dispersions, solid intermediate products and waterproof plastic products, thus allowing the simple production of novel products having homogeneously distributed agents, which exhibit, for example, an antimicrobial or barrier effect and/or have an absorbing capacity, such as with respect to oxygen, humidity, chemical, particularly gaseous compounds, or electromagnetic or radioactive radiation.
Claims26
A method of preparing an aqueous dispersion (D-III) comprising metal ions, characterized in that an aqueous dispersion (D-I) comprising metal salt nanogel is blended with an aqueous dispersion (D-II) of a polymerization product, polycondensation product or polyaddition product, and characterized in that a water-resistant product is produced when water is removed from the aqueous dispersion (D-III) when subjected to conditions to undergo at least partial coalescence.
