LIQUID AMINE TERMINATED DERIVATIVES OF DICLYCIDYL ETHERS (Docket No. 80,746-F) ABSTRACT OF THE DISCLOSURE Tetrafunctional amine derivatives of digyclidyl ethers of Bisphenol A that are liquid at ambient temperatures and that are useful as curing agents for epoxy resins are dis- closed together with the method by which they are prepared which comprises the steps of: dissolving the diglycidyl ether in a solvent (acetone or methyl ethyl ketone) and adding a polyoxyalkylene diamine in the mole ratio of about 4 to about 5 moles of the digly- cidyl ether per mole of said polyoxyalkylene diamine to provide an initial reaction mixture, heating the initial reaction mixture with agitation at a temperature of about 80° to about 160°C. for about 1 to about 4 hours sufficient to permit the diglycidyl ether to quantitatively react with the polyoxyalkylene diamine and to substantially completely volatilize the solvent to thereby form an intermediate reaction product, adding to the intermediate reaction product about 4 moles or more of a polyoxyethylene diamine per mol of initially used polyoxyalkylene diamine and heating the thus- formed second reaction mixture at a temperature of about 100° to about 150°C. for about 0.5 to about 5 hours, to form the tetrafunctional amine derivative.
