CA 2251301

NCO-terminated prepolymers are made by reacting a polymeric diphenylmethane diisocyanate (PMDI) and a polyol having a functionality of from about 1.8 to about 4.0 and a molecular weight of from about 400 to about 2,000. The PMDI and polyol are reacted in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 15:1 to about 160:1. These prepolymers are useful in the production of polyurethane foams, particularly laminated foams.
