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, C -C dicarboxylic acid or derivative with an amine having a general formula of R âNHâR âNHâR.
Process For Producing Phenol-Dicarbonyl Condensates With Increased Fluorescence, Epoxy Resins, Epoxy Resin Systems And Laminates Made With The Same
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.

Epoxy Resin Compositions, Processes Utilizing Same And Articles Made Therefrom
Disclosed are epoxy resin compositions which include an alkali metal containing cure accelerator. The alkali metal containing cure accelerators are preferably alkali metal hydroxides, alkoxides, carboxylates, or alkali metal salts. Articles prepared from the resin compositions of the invention exhibit enhanced thermal properties, and similar non-thermal properties, when compared to articles prepared from compositions including other accelerators such as imidazoles. The resin compositions of the invention may be used for any purpose, but are particularly suited to be utilized in the manufacture of laminates for printed circuit boards and non-electrical structural applications.

Abstract:
Compositions and methods for forming surfactants, aqueous dispersions, and curing agents are provided. In one aspect, the invention relates to improved epoxy functional surfactants prepared by reaction of an epoxy composition and an amidoamine composition formed from a blend of acid-terminated polyoxyalkylene polyols. The improved epoxy functional surfactants may be reacted with an excess of epoxy composition and water to result in an aqueous dispersion. The amidoamone composition may be a reaction mixture of a diamine compound and an acid terminated polyoxyalkylene composition formed from two or more polyoxyalkylene polyol compounds. The epoxy functional surfactant may be reacted with amine compounds to form a compound suitable as a curing agent.
