Abstract : This patent presents the synthesis of new diglycidyl ethers of polyhydroxy phenols, having all available aromatic hydrogen atoms substituted by fluorine. A specific example of a useful resin is the reaction product of 4,4'-dihydroxy-octafluorobiphenyl diglycidyl ether and tetrafluoro-m-phenylene diamine. The diglycidyl ethers and resins of this invention are particularly useful for fabricating coatings and glass fiber wound objects and are generally useful wherever water resistance, tough, non-flammable coatings are desired. Another advantage of the present diglycidyl ethers is their property of curing with various conventional and fluorinated curing agents to produce either thermosetting, thermoplastic, or elastomeric type compounds.
