权利人:US GOV AIR FORCE; US AIR FORCE
摘要:The present invention relates to a mechanochemical based synthesis of perfluoropyridine monomers, polymers made using such monomers and methods of making and using articles comprising such polymers. Such perfluoropyridine monomers are easily chemically tuned have the strength needed for high temperature applications and the flexibility needed for low temperature applications. In addition, to the aforementioned monomers, a mechanochemical based synthesis for such perfluoropyridine monomers is provided. All of the aforementioned performance application advantages are also found in polymers comprising Applicants' perfluoropyridine monomers.

摘要:Disclosed is a process comprising reacting CF3CCl2CF2CF3 (CFC-318ma) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CClâ•?CFCF3 (CFC-1317mx). Also disclosed is a process comprising reacting CF3CClâ•?CFCF3 (CFC-1317mx) with hydrogen in the presence of a dehalogenation catalyst to produce CF3C≡CCF3 (hexafluoro-2-butyne). Hexafluoro-2-butyne can be used to produce CF3CHâ•?CHCF2CF3 (1,1,1,4,4,5,5,5-octafluoro-2-pentene).

摘要:The synthesis of the fluorinated monomer, 2-((perfluoropyridin-4-yl)amino)ethyl methacrylate, and the use of the same in the preparation of fluorinated homo- and copolymers is provided. Such monomer was designed to contain a terminal methacrylate group, allowing for polymerization through free-radical techniques, both chain-growth and reversible addition-fragmentation chain-transfer methods. The monomer was designed to be compatible with other commercially available monomers and solvents to facilitate ease of copolymerization through free-radical polymerization techniques. The polymerization does not require perfluorinated alkyl substances or perfluorooctanoic acids or related compounds in the synthesis of the fluoropolymers.
