Abstract

Thermosetting polymers are obtained by heating an a ,o -diisocyanatoalkane in the absence of water in an inert atmosphere and in the presence of a cyclic trimer of a phosphinoborane of formula <FORM:0984708/C3/1> where R is an alkyl group, and X and X1 are hydrogen or halogen atoms. From 1 to 5% of the trimer, based on the weight of the diisocyanatoalkane, may be used, and the mixture may be heated to 150 DEG to 250 DEG C.; a diluent may or may not be present. Carbon dioxide is evolved but the polymer contains a part of the oxygen initially present in the isocyanate groups. In examples, polymers are obtained by heating 1,6-diisocyanatohexane in the presence of the trimer of dimethylphosphinoborane.
