Active Polymer Modification of Bitumen for Use in Roofing Materials
A modified bitumen consisting of a polyurethane wherein the polyisocyanate or polyisocyanate-dominated polyurethane prepolymer (or prepolymers) is first reacted with the bitumen to take advantage of the bitumen's hydroxyl and amine functionality and form an isocyanate-bitumen adduct to form a w...
