Diglycidyl ether of bisphenol F

Gamma irradiation curing of epoxy resins for structural adhesives — Radiation cure polymerization of commercial diglycidyl ether of bisphenol F epoxy resin has been achieved using Co-60 irradiation source, compounding the monomer with and onium salt catalyst [9],... 

Materials. The diglycidyl ether of bisphenol F (DGEBF), and N,N,N ,N -tetraglycidyl-4,4 -diaminodiphenylmethane (TGDDM), were received from Ciba Geigy. 4,4-diaminodiphenylmethane (DDM), was obtained fi om Aldrich. 4,4 -diaminodiphenylsulphone (DDS), was provided from Sigma Chemical. All chemicals were used without further purification. The monomers are presented in Figure 1. 

In epoxy materials, some of the conventional diglycidyl ether of bisphenol F has been replaced with functionalized vegetable oils, such as epoxidized linseed oil and epoxidized soybean oil. The materials have been cured using an anhydride based curing agent.

Figure 4 shows the chemical formulae of other epoxy resins commonly used to prepare conductive adhesive compositions. Representative of approximately difunctional compounds are the diglycidyl ether of bisphenol-F (DGEBF) 18 and the diglycidyl ether of 1,3-dihydroxybenzene 19. Epoxy resins with a functionality higher than two are prepared by the reaction of l-chloro-2,3-epoxypropane 7 with polyfunctional starting materials.
