ABSTRACT:
A catalyzed polyurethane reactive hot melt adhesive is prepared from a reactive polyurethane prepolymer and 0.05 to 0.6% by weight of a 2,2'dimorpholinoethyl ether or di(2,6-dimethylmorpholinoethyl)ether catalyst. The adhesive is characterized by improved curing speed with little or no effect on the thermal stability.
