ABSTRACT:
An aminated, hydroxylated, polyester polyol resin comprised of the product of a reaction of an acid anhydride selected from the group including maleic acid anhydride or a mixture of maleic acid anhydride and a polyfunctional acid anhydride, a low molecular weight polyether polyol having an average molecular weight of about 100 to about 600, selected from the group including diethylene glycol or a mixture of diethylene glycol and another low molecular weight polyether polyol, a lower alkylene oxide and having from 2 to 4 carbon atoms, and a mono- or di-functional amino compound selected from the group including diethanolamine or a mixture of diethanolamine and at least one mono- or di-functional amino compounds containing at least one isocyanate reactive group attached to the nitrogen of the mono- or di- functional amino compound. The aminated, hydroxylated, polyester polyol resins are particularly useful forming a thermosetting composition comprising the aminated, hydroxylated, polyester polyol resin and polyisocyanate in reaction injection molding process to prepare molded articles.
