| The epoxy resin industry is based on the polymerisation of a diphenol and a diepoxide, usually "bisphenol A and bisphenol A diepoxide".The overall process requires a chlorine/caustic facility and twelve chemical transformations. Recently, bisphenol A, also a comonomer for polycarbonate resins,was found to produce chromosomal abnormalities in a laboratory mouse colony, hence a potential toxicity issue.[P. Hunt, Curr. Biol.,Vol. 13, 546,(2003)].This paper will describe the synthesis of novel diepoxides from o-allylphenols as well as N,N"-disubstituted disulfonamides. The potential process and cost advantages of these materials relative to bisphenol A technology will be dicussed. In addition, the chemistries for the synthesis of resins wherein a N,N"-disubstituted disulfonamide is copolymerized with either an organic dicarbonyl dichloride moiety or an isocyanate will be described. |
