Abstract
The instant invention is a device for producing dispersions and method of producing dispersions. The device for producing dispersions includes a first stator, a second stator, a shell encasing the first stator and the second stator, a rotor being disposed therebetween the first stator and the second stator thereby forming a first chamber and a second chamber, at least one first inlet port into the first chamber, and at least one outlet port out of the second chamber. The device may optionally include at least one additional second inlet port into the second chamber. The method of producing a polyurethane dispersion includes the following steps: (1) providing a device for producing a dispersion including a first stator, a second stator, a shell encasing the first stator and the second stator, a rotor being disposed therebetween the first stator and the second stator thereby forming a first chamber and a second chamber, at least one first inlet port into the first chamber, at least one outlet port out of the second chamber; and optionally one or more additional second inlet ports into the second chamber; (2) introducing a prepolymer phase and an aqueous phase into the first chamber v…
