Abstract
The invention comprises compounds of the general formula <FORM:1108128/C3/1> wherein n is an integer from 2 to 20. The compounds are prepared by reacting hexafluoropropylene with a compound of the formula <FORM:1108128/C3/2> under anhydrous conditions in the presence of an inert polar solvent and of an alkali metal, silver or quaternary ammonium fluoride to give a compound of the formula <FORM:1108128/C3/3> which is converted to the desired product by (i) pyrolysis in the presence of an alkali metal carbonate or zinc oxide, or (ii) by reaction with an aqueous alkali metal hydroxide to give the corresponding carboxylic acid salt which is then dried and pyrolysed. The diacyl fluoride starting material is prepared by reacting tetrafluoroethylene epoxide with oxalyl fluoride in an inert solvent and in the presence of a quaternary ammonium fluoride formed in situ by adding the corresponding cyanide to the reaction system. The compounds of the invention may be converted to thermoset resins consisting essentially of recurring units of the formula <FORM:1108128/C3/4> wherein the unsatisfied valency bonds are linked to other of the same units, by polymerization at 20-250 DEG C. at atmospheric or under autogenous pressure and in the presence of a free radical polymerization initiator. Reference has been directed by the Comptroller to Specifications 952,281 and 1,033,919.ALSO:The invention comprises compounds of the general formula <FORM:1108128/C2/1> wherein n is an integer from 2 to 20. The compounds are prepared by reacting hexafluoroproylene with a compound of the formula <FORM:1108128/C2/2> under anhydrous conditions in the presence of an inert polar sovent and of an alkali metal, silver or quaternary ammonium fluoride to give a compound of the formula <FORM:1108128/C2/3> <FORM:1108128/C2/4> which is converted to the desired product by (i) pyrolysis in the presence of an alkali metal carbonate or zinc oxide; or (ii) by reaction with an aqueous alkali metal hydroxide to give the corresponding carboxylic acid salt which is then dried and pyrolysed. The diaryl fluoride starting material is prepared by reacting tetrafluoroethylene epoxide with oxalyl fluoride in an inert solvent and in the presence of a quaternary ammonium fluoride formed in situ by adding the corresponding cyanide to the reaction system. Compounds of the formula <FORM:1108128/C2/5> where R is -CF3 or -C4F9, used as free-radical polymerization initiators, are prepared by reaction of CF3-CC-R with N2F4. Reference has been directed by the Comptroller to Specifications 1,033,919 and 952,281.
