Title: Production of aqueous polymer dispersion
Inventor: MATSUMOTO TSUNETAKA
IPC: G01N33/545
Filed: 1982-06-07
Abstract: PURPOSE:To enhance the stability or the like of an emulsion by adding a basic substance to an organic solvent-containing emulsion of an ethylenic polymer having acidic electrolytic groups, distilling off the organic solvent to thereby localize the acidic electrolytic groups on the surfaces of polymer particles. CONSTITUTION:An ethylenically unsaturated monomer (A) such as styrene and an unsaturated monomer (B) containing an acidic electrolytic group such as a carboxyl group (e.g., acrylic acid) are emulsion-polymerized in an aqueous medium and an organic solvent in which component (B) has a partition coefficient between the organic solvent and water of not less than 2 (e.g., butyl alcohol or methyl isobutyl ketone). Then, a basic substance (e.g., caustic soda or ammonia) is added to the produced emulsion, and the organic solvent in the emulsion is evaporated by steam distillation. In this way, the acidic electrolytic groups are located on the surfaces of polymer particles to obtain the purpose aq. polymer dispersion excellent in stability and reactivity.
