Aqueous Polyurethane Microgel Dispersion |
| abstract |
The invention describes a method of forming a stable aqueous polyurethane microgel dispersion comprising preparing an oil phase comprising a gel-forming polyol and an isocyanate in approximately stoichiometric proportion by blending the polyol and isocyanate for a time, less than the gel time of the polyol and isocyanate, thereby forming a homogeneous flowable liquid mixture; providing a water phase comprising a surfactant dispersed in water; combining the water phase with the oil phase flowable liquid mixture and subjecting the combined water and oil phases to high shear agitation to form an aqueous emulsion of micro-size droplets of the oil phase flowable mixture in water; and agitating the emulsion for a time sufficient for the micro-size droplets to polymerize, forming a stable aqueous suspension of solid polyurethane micro-size gel particles. The resultant aqueous suspension of solid polyurethane micro-sized gel particles is substantially free of isocyanate monomer, and is a shelf-stable aqueous suspension of solid polyurethane micro-size gel particles in water. Optionally, a benefit agent is incorporated during or after formation of the microgel dispersion. |
