F-3 Methylbutene-1 has been oxidized using oxygen and ultraviolet radiation to form polycarbonyl fluoride oligomers. The formation of fluoroformate terminated material is insignificant. This is in sharp contrast to the products derived from the prior art oxidation of F-propene HFP in which up to 60 fluoroformate terminated materials was produced. F-Ethylene TFE can be added to the F-3 methylbutene-1 reaction gas stream without adversely affecting the product composition. The fluoride oligomers, after addition of one unit of hexafluoropropylene oxide, can be converted to striazines which have excellent properties as hydraulic fluids. Author
