A polymer concentration of 50% by volume or more based on the polymer dispersion by free radical emulsion polymerization of ethylenically unsaturated monomers excluding vinyl halides and vinylidene halides in the presence of at least one initiator and at least one initial polymer The process for preparing a low viscosity polymer water dispersion includes emulsifying most of the monomers in the water polymer of the initial polymer and feeding the emulsion continuously to the polymerization reaction. |
