  • Polymeric MDI prepolymer composition and flexible foams prepared therefrom
    Patent number: 6090864
    Abstract: The present invention relates to prepolymers, comprising(a) a polymethylene polyphenylene polyisocyanate; and(b) a polyether polyol having an average hydroxyl equivalent weight of at least about 700;wherein the resulting prepolymer has an average viscosity of between about 400 to about 2000 centipoise at 25.degree. C. The prepolymer is useful, for example, for the production of polyurethane foams and, more particularly, to medium density flexible foams having superior flow characteristic and fast demold times.
