ABSTRACT:
Disclosed are novel storage stable liquid compositions derived from heating a liquefied methylenebis(phenyl isocyanate) with a minor proportion of a cycloalkane diol.
The molded polyurethanes produced using the above liquid isocyanates are characterized by excellent resistance to elevated temperatures. In fact, their heat resistance is superior to similarly constituted prior art materials.
