Abstract
PURPOSE: To obtain the title rigid foam of uniform, fine-cellular structure, having high heat resistance and outstanding flame-retardency, by the reaction, is the presence of a catalyst, a blowing agent, etc., between an organic polyiscyanate and a polyol consisting chiefly of a phosphoroamidate.
CONSTITUTION: The objective rigid foam can be obtained by the reaction, in the presence of a catalyst, a blowing agent, and a foam stabiliaer, between 9a) an organic polyisocyrate and (b) a polyol having 0.2W0.8 equivalent, per equivalent of the isocyanate group of the component (a), of hydroxyl group, consisting chiefly (i.e., 30W100 wt%) of a phosphoroamidate of formula (R1 and R2 are each lower alkyl or lower haloalkyl independently, R3 is hydroxy lower alkyl, R4 is H or hydroxy lower alkyl).
