Procedure

0.2 part by weight of the sodium salt of a sulfated addition product of triisobutylphenol and 7 mols of ethylene oxide (emulsifier A) and 0.02 part by weight of potassium peroxodisulfate are dissolved in 61.5 parts by weight of completely desalted water at 80° C. in a polymerization vessel provided with a reflux condenser, stirrer, thermometer, and feed vessel. An emulsion, earlier prepared from 83 parts by weight of ethyl acrylate, 10 parts by weight of methoxy polyethyleneglycol methacrylate [formula (I), n=15], 5 parts by weight of disodium itaconate, 1.2 parts by weight of N-hydroxymethyl methacrylamide, 0.8 part by weight of methacrylamide, 2.3 parts by weight of emulsifier A, 1 part by weight of the addition product formed between isononylphenol and 100 mols of ethylene oxide (emulsifier B), 0.18 part by weight of potassium peroxodisulfate, and 94 parts by weight of desalted water, is added dropwise to this solution at 80° C. over a period of 4 hours. After addition is complete, the reaction temperature is kept for one further hour at 80° C. and subsequently the mixture is cooled to room temperature. A coagulate-free dispersion having a solids content of about 40% is obtained.
