ABSTRACT:
A moisture-curable, hot melt composition comprising a graft polyurethane prepolymer made by reacting a macromonomer, polyol, polyisocyanate and optional silane reagent is provided. The composition advantageously provides adhesives having initial creep resistance, short set times, and long open times.
