Abstract

PURPOSE: To improve the heat resistance and toughness of titled composition, by employing as essential components, an isocyanate compound and an alkylene adduct of the reaction product between an ethylenic carbon bond-containing dicarboxylic acid and a polyamine.
CONSTITUTION: An ethylenic carbon bond-containing unsaturated dicarboxylic acid, an anhydride thereof or a functional derivative thereof is mixed and reacted with a polyamine to produce a compound (hereafter described as DCPA). An alkylene oxide is added to the DCPA in the presence of a basic catalyst to produce a polyol. As compared with conventional polyurethanes, a polyurethane composition which contains, as essential components, said polyol and an isocyanate compound, and prepared by curing the polyol with the isocyanate compound is excellent in heat resistance, toughness, reactivity, flame retardancy and dimentional stability.
