Abstract: The present invention provides a process for producing phenol-dicarbonyl condensates high in fluorescence by reacting a phenolic compound with a 1,2-dicarbonyl compound in the presence of a catalyst selected from one or more carboxylic acid(s) or one or more carboxylic acid precursor(s). The present invention further provides phenol-dicarbonyl condensates, epoxy resins, epoxy resin systems and laminates prepared using these phenol-dicarbonyl condensates.

Abstract: A curable epoxy composition comprises an epoxy resin having at least 1.5 epoxy groups per molecule and an amine-terminated polyamide. The liquid amine-terminated polyamide is prepared by reacting a long-chain, C20-C60 dicarboxylic acid or derivative with an amine having a general formula of R1—NH—R2—NH—R3.

Abstract: A amidoamine composition containing oligomeric amidoamine compounds having the structure: 1

Abstract: An epoxy resin composition containing a) an epoxy resin and b) a liquid amine terminated polyamide curing agent prepared by condensing an aminoalkylpiperazine and a dicarboxylic acid. The epoxy resin composition typically requires less than 35% of solvent to produce a sprayable viscosity. The cured epoxy composition has good flexibility. A hydroxy-functional flexibilized resin is also produced by reacting (a) an epoxy resin, (b) a liquid aminoalkylpiperazine-based amine terminated polyamide and (c) a hydroxy-functional amine.

Abstract: A new and improved bulk sandwich package and method of packaging and merchandising is provided. A plurality of sandwiches are individually wrapped in gas permeable wrap and then bulk packaged in a modified atmosphere process, refrigerated and distributed to store locations or merchandisers where the bulk packages are refrigerated until needed, opened and placed in a refrigerated merchandiser for sale. The refrigerated merchandiser therefore provides consumers with a deli-style sandwich in stores without kitchen facilities, and permits the self-service purchase of the pre-assembled sandwiches.

Abstract: A new and improved biscuit sandwich and method of packaging and merchandising is provided. A biscuit with high fat content of about 20% by weight is individually wrapped in the form of a biscuit sandwich packaged in a modified atmosphere process, refrigerated and distributed to store locations where it can be reheated and placed in a heated merchandiser for sale. The heated merchandiser therefore provides consumers with a home-style biscuit sandwich in stores without cooking facilities, and permits the self-service purchase of the pre-cooked and reheated biscuit sandwiches.

Abstract: A substrate is coated or impregnated with a composition comprising an a) epoxy resin, b) a liquid amine-terminated polyamide curing agent prepared by condensing an aminoalkylpiperazine and a long-chain dicarboxylic acid, ester or chloride, and c) water.

Abstract: An epoxy resin composition containing a) an epoxy resin, b) a liquid amine terminated polyamine curing agent prepared by condensing an aminoalkylpiperazine and a dicarboxylic acid, and (c) water. An aqueous dispersion of the amine terminated polyamine curing agent used in this invention is useful as a curing agent for water borne applications.

Abstract: An amine curing agent composition for an epoxy resin is provided having low volatility and good processability containing a) a polyamine curing agent and b) an aliphatic alcohol-alkylene oxide adduct. An epoxy resin-polyamine curing agent system containing an aliphatic alcohol-alkylene oxide adduct is also provided.

Abstract: The solution stability of a modified bisimide resin is enhanced by partially polymerizing a mixture of a bisimide monomer and a reactive triene which contains a conjugated double bond capable of Diels-Alder reaction with the bisimide. Such partial polymerization of a bisimide with a reactive triene such as myrcene provides a modified bisimide having good solubility in an organic solvent.
