| Abstract: | The NCOCH2(CF2)6CH2OCN fluoromethylene cyanate ester monomer and resin are synthesized and characterized. The monomer is prepared by a large‐scale bench‐top synthesis, characterized by differential scanning calorimetry, infrared, 1H‐, 13C‐, 15N‐, and 19F‐NMR spectroscopies and analyzed for catalytically active impurities. Conversion of the monomer to prepolymer and cured resin is characterized by IR and NMR spectroscopies and kinetically analyzed. Resin properties characterization includes thermal, tensile, dynamic mechanical, dielectric, refractive index, thermodielectric and thermogravimetric stabilities, and water absorption. Relevant property comparisons with the commercial AroCy F cyanate ester resin (6F bisphenol A dycyanate) and a Jeffamine‐bisphenol diglycidyl ether epoxy are made. © 1999 John Wiley & Sons, Inc.
