Abstract:
A method for deblocking a blocked isocyanate is described herein. The method includes contacting a blocked isocyanate and a halide ion source under conditions effective to provide a deblocked isocyanate. A method of making a polyurethane is also disclosed. The method of making a polyurethane includes combining a blocked isocyanate, a polyol, and a halide ion source in the presence of solvent and under conditions effective to provide the polyurethane.
