<p>The present invention relates to processes for preparing carboxylated latex particles based on the copolymerization of a monoalkenylaromatic monomer (A) and an aliphatic unsaturated carboxylic acid (B), where the copolymerization takes place at a pH in the range from pH > 1.5 to pH < 4.5. The pH is preferably monitored during the copolymerization process and regulated by suitable compensatory titration. The invention likewise relates to the carboxylated latex particles obtainable by one of the processes according to the invention, and to the use of these particles in an immunological test method.</p>
