  • Patent number: 6103786
    Abstract: Stable polymer dispersions with polymer particle sizes of 0.1 to 10 .mu.m are prepared by dissolving a water-in-oil emulsion, comprising a polymer dissolved in an organic solvent which is immiscible with water (organic phase) and an aqueous phase, wherein the viscosity of the organic phase is 1.0 to 20,000 mPas (measured at 25.degree. C.), the surface tension between organic and aqueous phase is 0.01 to 30 mN/m, the particle size of the water emulsified in the organic phase is 0.2 to 50 .mu.m and the ratio by volume of organic phase to aqueous phase is in the range 80:20 to 20:80, subjecting this emulsion to a shear process at a shear power of 1.times.10.sup.3 to 1.times.10.sup.8 Watts per cm.sup.3, wherein the water-in-oil emulsion is converted into an oil-in-water emulsion.
