Perfluoro group-containing compounds and hardened polymer of the same

Methods for producing perfluorocarbon monomethanols or dimethanols are disclosed. The methods of the invention can provide branched perfluorocarbon monomethanols or dimethanols with good purity and yields.

Method for preparing perfluorocarbon-substituted methanols

This invention pertains to a method for liquid phase fluorination for perfluorination of a wide variety of hydrogen-containing compounds.

Liquid-phase fluorination

This invention pertains to a method for liquid-phase fluorination for perfluorination of a wide variety of hydrogen-containing compounds.

Liquid phase fluorination

This invention pertains to perfluoropolyethers and perhalogenated chlorofluoroether polymers that can be prepared by fluorinating polymers made by the polymerization of acetals, ketals, polyacetals, polyketals and orthoesters with elemental fluorine.

Fluorination of acetals, ketals and orthoesters

This invention pertains to perfluoropolyethers and perhalogenated chlorofluoropolyethers that can be prepared by fluorinating addition polymers made by polymerizing epoxides.

Perfluorinated polyethers

Perfluoropolyethers and perhalogenated chlorofluoroether polymers are disclosed that can be prepared by fluorinating polymers made by the polymerization of acetals, ketals, polyacetals, polyketals and orthoesters with elemental fluorine.

Perfluorinates polyethers

A method of producing perfluorocarbon halides in a one-pot reaction is described. The method employs a perfluorocarbon acid, a first halogenating agent and a second halogen which drives the reaction forward. Novel perfluorocarbon halides and a direct method for producing perfluorocarbon hypohalites also are described.
