Abstract:
Embodiments of the present disclosure are directed to polyurethane prepolymers, more particularly, to polyurethane formulations including a polyurethane prepolymer that can form polyurethanes. As an example, a polyurethane formulation can include a polyurethane prepolymer and a polyol composition including polyols, water, and a catalyst, where the polyurethane prepolymer is a reaction product of a monol and an excess amount of a polyisocyanate.

Claim (Index 9):
A method for forming a polyurethane formulation, comprising:\n preparing a reaction mixture that includes a monol and an excess amount of a polyisocyanate and allowing the reaction mixture to react to form a polyurethane prepolymer, where the monol is from 0.5 weight percent (wt %) to 30 wt % of a total wt % of the reaction mixture and where the polyisocyanate is from 10 wt % to 85 wt % of the reaction mixture, and where the monol is from 1 wt % to 60 wt % of constitutional units derived from ethylene oxide (EO); and adding a polyol composition including polyols, a catalyst, and water to the reaction mixture after formation of the polyurethane prepolymer to form a polyurethane formulation, where the polyurethane formulation has an isocyanate index in a range from 50 to 120, wherein all hydroxyl groups of the monol are reacted with an excess number of isocyanate groups of the polyisocyanate prior to adding the polyol composition.
