    摘要: Reactive diluents comprise the amide and/or imidazoline reaction products of low molecular weight carboxylic acids, such as acetic acid, and polyalkyleneamines, such as 2-aminoethylpiperazine (AEP) and triethylenetetramine (TETA). The reactive diluents are prepared by condensation reaction of the carboxylic acid and the polyalkyleneamine at elevated temperature generating a mixture of unreacted polyalkyleneamine, amides and/or imidazolines. The reactive diluent reaction products are used to reduce the viscosity of high viscosity polyamidoamines prepared from fatty dimer acids and polyethyleneamines. Also disclosed is an epoxy composition comprising the epoxy curative composition of a polyamidoamine curing agent reduced in viscosity by the addition of the reactive diluent reaction product and an epoxy resin, such as the diglycidyl ether of bisphenol A.

    摘要: This invention relates to improved one part polyepoxide resins which are tough and have enhanced flexible and elastic properties. The polyepoxide resins comprise a polyepoxide resin based on a polyglycidyl ether of a phenol, an oxazolidone toughener and a latent amine curative. The improvement in the polyepoxide resin formulation comprises incorporating an oxazolidone toughener represented by the formula:

    wherein R is the residue of an aliphatic glycol or aliphatic ether glycol having from 2 to 20 carbon atoms.
