Abstract:

A process for the preparation of an inert terpolymer of allyl acrylate -acrylic acid - methyl acrylate, which on addition of tetrafluorohydrazine produces a polymer equivalent to NFPA prepolymer, has been developed. Thus, the handling of the hazardous intermediates in the production of NFPA prepolymer can be avoided. The continuous-process reactor for the preparation of the geminal bisdifluoramino adduct of trifluoroacetoxy acetone, the precursor of geminal NFPA, has been modified. The new reactor provided yields of 88 of the desired geminal bisdifluoramine. A successful synthesis of all geminal bisdifloramine plasticizers with an NF content of 60 has been worked out. A polyhydroxy compound, ethylene glycol, glycerol, or pentaerythritol is converted to the poly-propargyl ether. Hydrolysis of the acetylene functions provides a poly-ketone that can be difluoraminated smoothly with difluoramine-sulfuric acid. The synthesis of a nylon-6 type monomer, 5,5-bis difluoramino-2-azacycloheptanone, has been completed. Degradation studies on related caprolactams are also reported.
