ABSTRACT:
An aqueous artificial resin dispersion, comprising an aqueous phase and a water-insoluble disperse phase formed from particles containing a copolymer formed in substantial part from a water insoluble or slightly soluble first monomer, wherein the copolymer additionally is formed from a second monomer of the formula ##STR1## wherein R represents hydrogen or methyl, R' represents hydrogen or an alkyl radical with 1 to 12 C-atoms, R" represents an alkyl radical with 7 to 20 C-atoms, and M represents a proton, an alkali metal ion, or an ammonium ion, with the proviso that the aqueous phase is free of low molecular weight, ionic emulsifying agents. Such dispersions are particularly well suited for continuous emulsion polymerization because of the highly stable monomer emulsions formed by mixtures produced according to the invention.
