Abstract: Formulations comprising an isosorbide-modified unsaturated polyester comprising maleic acid, fumaric acid, itaconic acid or maleic anhydride and isosorbide and one or more low profile additives. The formulations exhibit better shrink control in molding compound formulations with standard low profile additives than their non-isosorbide-modified analogues. These isosorbide-modified unsaturated polyester resins may be applied in molding compounds like sheet molding compounds or bulk molding compounds and may be components of fiber reinforced composites or other composite materials.

Abstract: The present disclosure relates generally to resin formulations for sheet molding compounds. Particularly, but not by way of limitation, the invention relates to low-density thermosetting sheet molding compounds (SMC) comprising an organic-modified, inorganic clay, a thermosetting resin, a low profile agent, a reinforcing agent, a low-density filler, and substantially the absence of calcium carbonate. The present disclosure relates particularly to blends of isophthalate modified, maleic-glycol polyester resin -glycol and maleate-glycol polyester resins that provide low density, thermosetting SMC that yields exterior and structural thermoset articles, e.g. auto parts, panels, etc that have Class A Surface Quality.

Abstract: A laminate formed from a first fiber-reinforced ply joined by a laminating resin composition to a second fiber-reinforced ply. The laminating resin composition is the cured residue of a polyester resin being end-terminated with an alkyl acrylate group and diluted with less than about 35 wt-% styrene. The first fiber-reinforced ply is laminated to the second fiber-reinforced ply with the laminating resin composition by coating a surface of the first ply with an adhesive composition. The coated first ply surface is joined with a surface of the second ply and the adhesive cured. In making the laminating resin composition, unreacted alkyl acrylate can be reacted with an epoxy to push the reaction to completion.

Abstract: The present invention provides a process for the preparation of low styrene content resins prepared by first reacting an unsaturated carboxylic acid, its corresponding anhydride or mixtures thereof with a monohydric alcohol, DCPD and water and reacting the product of the first step with a polyol and optionally an oil containing unsaturation, its corresponding fatty acid or mixtures thereof.

Abstract: The invention relates to a process for preparing polyester resins by first reacting a carboxylic acid or its corresponding anhydride with a saturated monohydric alcohol to form the half ester and then reacting the half ester with a polyol. In addition to the polyol, up to 45 wt % of all oil containing unsaturation can be present in the second step.

Abstract: A method is provided for improving high temperature performance grade properties of unblown asphalt by i) heating an asphalt cement to 200.degree. F. to 500.degree. F. (93.degree. C. to 260.degree. C.), ii) adding 0.1 wt. % to 10 wt. % ethylene-vinyl acetate copolymer based on weight of said asphalt cement to the heated asphalt cement, iii) adding 0.05 wt. % to 1.0 wt. % phosphorus-containing acid, e.g., polyphosphoric acid, based on weight of said asphalt cement and iv) mixing the resulting blend, thereby providing an unblown asphalt composition of greater useful temperature index (UTI). The invention further relates to asphalt compositions thus made and paving compositions containing these asphalt compositions.

Abstract: A method is provided for improving high temperature performance grade properties of asphalt which comprises i) heating an asphalt cement to 200 to 500.degree. F. (93 to 260.degree. C.), ii) adding 1 to 10 wt. % crosslinkable polymer, e.g., styrene-butadiene-styrene triblock copolymer based on weight of said asphalt cement, iii) adding a useful temperature index (UTI) improving amount of dioxime(s) of 1,4-benzoquinone and its derivatives and optionally, free radical initiator, e.g., organic peroxide, and iv) mixing the resulting blend, thereby providing a paving asphalt having a greater useful temperature index (UTI) than a corresponding blend to which no dioxime is added. The invention further relates to asphalt compositions thus made and paving compositions containing these asphalt compositions.

Abstract: The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from .gtoreq.1:1 to .gtoreq.13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
