A method for preparing fluoroalkylsulfonyl imides by reacting a fluoroalkylsulfonamide with a fluoroalkylsulfonyl halide or a fluorosulfonyl halide in the presence of a non-nucleophilic base. One reaction is:

Preparation of bis (fluoroalkylenesulfonyl) imides and

Fluorochemical oxazolidinone compositions are provided. They are normally solid, water-insoluble, fluoroaliphatic radical-containing 2-oxazolidinone compounds which have one or more 2-oxazolidinone moieties, at least one of which has a monovalent fluoroaliphatic radical bonded to the 5-position carbon atom thereof by an organic linking group.

Fluorochemical oxazolidinones

Fluorochemical oxazolidinones compositions are provided. They ar normally solid, water-insoluble, fluoroaliphatic radical-containing 2-oxazolidinone compounds which have one or more 2-oxazolidinone moieties, at least one of which has a monovalent fluoroaliphatic radical bonded to the 5-position carbon atom thereof by an organic linking group.

Cationic and non-ionic fluorochemicals, mixtures of cationic and non-ionic fluorochemicals, blends of the mixtures with fluorochemical poly(oxyalkylenes), and compositions of the fluorochemicals with hydrocarbon nonionic surfactants are provided. These fluorochemicals and compositions, in dispersions, emulsions and microemulsions, may be applied to porous fibrous substrates to give oil and water repellancy and soil resistance.

Cationic and non-ionic fluorochemicals and fibrous substrates treated

Coordination compounds of rhodium are solid salts having donor ligands of [(aryl).sub.3 P].sub.3 Rh.sup.+ and a non-coordinated counterion derived from a fluorochemical acid, the salts having the formula:

Fluorochemical rhodium compounds

Fluorochemical copolymers, useful as wet-end papermaking additives which impart oil and water repellency and food stain resistance to ovenable paperboard under food cooking conditions, and as a treatment for imparting oil and water repellency to textile fibers. The fluorochemical copolymers are derived (by weight) from about 60 to 80% fluorochemical acrylate, 1 to 30% halogenated alkyl or alkoxyalkyl acrylate, 1 to 15% glycidyl acrylate or methacrylate, 1 to 6% of certain cationic acrylates or methacrylates, and 0 to 20% vinylidene chloride.
