CATALYSTS FOR THE CURING OF A WATER-CURABLE ISOCYANATE-FUNCTIONAL PREPOLYMER Abstract New catalysts useful in the curing of a water-curable isocyanate-functional prepolymer are provided. The new catalyst is a new 2,2'-dimor- pholinyldialkyl ether. The use of the improved catalyst provides prepolymer/catalyst premix compositions having equivalent or increased shelf stability and which, when water-cured, yield resins having superior early strengths. A method of curing an isocyanate-functional prepolymer and articles useful as orthopedic bandages are also provided.
