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.

Aminated hydroxylated polyester polyol resin and molding compositions

A thermosetting resin composition comprising the product of an unsaturated polyester intermediate resin which is derived from the reaction of (a) an acid anhydride selected from the group including maleic acid anhydride or a mixture of maleic anhydride and a polyfunctional acid anhydride, a low molecular weight polyether polyol having a molecular weight of about 100 to about 600 selected from the group including diethylene glycol or a mixture of diethylene glycol and at least one other low molecular weight polyether polyol having a molecular weight of about 100 to about 600, and a lower alkylene oxide having from 2-4 carbon atoms; and, (b) a mono- or di-functional amino compound selected from the group including diethanolamine or a mixture of diethanolamine and at least one other mono- or di-functional amino compounds selected from the group including a primary or secondary amino alcohol or a primary or secondary diamine which contain isocyanate reactive groups attached to the nitrogen of the amino alcohol or diamine, the equivalent ratio of mono- or di-functional amino compound to unsaturated polyester intermediate resin being in the range from about 0.125 to about 0.5, such that a corresponding proportion of the unsaturated polyester intermediate resin remains unreacted and has a maleate functionality; (c) a morpholine compound; (d) a vinyl crosslinking compound; and (e) an isocyanate. The thermosetting resin compositions are especially useful in a reaction injection molding (RIM) process to prepare molded articles.

A woven or non-woven mat comprising natural or synthetic fibers bonded together with the residue formed by removing water from an aqueous composition comprising a thermoplastic emulsion and a melamine formaldehyde resin forms an underlay for asphalt paving for road surfaces.

Mats for asphalt underlay

The reaction products of bisphenol-A and phthalic anhydride or the brominated derivatives thereof a glycol and/or propylene glycol is employed to produce low flame spread urethane-modified isocyanurate foams.
