Abstract: 1,135,078. Epoxy resins. ALLIED CHEMICAL CORP. 17 Aug., 1966 [18 Aug., 1965], No. 36835/66. Heading C3B. Curable epoxy resins are produced by α,α 1 ,α 11 - tris - (hydroxyphenyl) - 1,3,5 - triisopropylbenzene, 2,2 - bis - (p hydroxyphenyl) - propane and epichlorohydrin in the presence of alkali. The resin may be purified by solution in an organic solvent, washing with water, distillation to remove the solvent, solution in acetone, filtration and recovery. The resins may be cured with conventional curing agents, modified by reaction with aminoplasts and phenoplasts and mixed with solid epoxy resins of higher epoxide equivalent. They are useful as adhesive and casting resins.

Abstract: Curable epoxy resins are produced by reacting a ,a 1,a 11 - tris - (hydroxyphenyl) - 1,3,5-tri-isopropylbenzene, 1,4 - bis - (p - hydroxycumyl) - benzene and epichlorohydrin in the presence of an alkali. Preferably the reaction is performed in the presence of water and using an excess of epichlorohydrin as solvent. The epoxy resin is then recovered by filtering the reaction mixture, distilling off the excess epichlorohydrin, dissolving the resin in acetone, filtering and removing the acetone. The resins may be cured by means of the conventional curing agents for epoxy resins and modified by reaction with urea-, melamine- or phenolformaldehyde resins.
