Abstract
The emulsion polymerization of free-radical-polymerizable monomers in the presence of a branched, poly(ethylene oxide) having a molecular weight of 4,000 to 19,000 and 1 to 250 mmol of the sum of the alkali metal and ammonium ions which are not bound to the emulsifier per liter of aqueous phase provides coarse, aqueous plastic dispersions. The process allows for the effective control of the particle size in the dispersion and yields carboxylated rubber dispersions which are suitable for the production of coating materials for carpets and paper.
