ABSTRACT:
The invention provides a process for the preparation of large-particle, aqueous plastic dispersions, which permits targeted adjustment of particle size. The process comprises a system which controls the particle size and comprises the step of polymerizing a monomer in the presence of an anionic emulsifier; a substantially non-branched, nonionic, water-soluble polymer auxiliary; and alkali metal and/or ammonium ions not bonded to emulsifier. The polymer auxiliary can be prepared reproducibly with regard to its agglomerating effect.
