Patent ID: 7153902

Claim:
A process for preparing a water-continuous emulsion of an elastomeric polymer that is essentially free of organic solvents and having a solids content of greater than 75%, an average particle size less than 5 μm, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising the steps of: (I) forming a premix comprising; (A) 100 parts of an elastomeric polymer having a viscosity of 0.5 to 1,000,000 KPa-s and a glass transition temperature up to 50° C. (B) 3 to 30 parts of a surfactant, wherein the premix is essentially free of organic solvents, (II) adding (C) 5 to 45 pans water to the premix with mixing thereby forming the water-continuous emulsion of the elastomeric polymer.
