Fluorochemical oxazolidinones

Film comprising a film-forming synthetic organic polymer and a fluorochemical oxazolidinone composition comprising normally solid water-insoluble, fluoroaliphatic compounds comprising one or more 2-oxazolidinone moities, ##STR37## at least one of which has a monovalent fluoroaliphatic radical, R.sub.f, which is a fluorinated, stable, inert non-polar, oleophobic, hydrophobic radical having 3 to 20 carbon atoms and 40 to 78 weight percent fluorine and the terminal portion of which has at least three fully fluorinated carbon atoms, bonded to the 5-position carbon atom thereof by an organic linking group, Q.

A molded article comprising a synthetic organic polymer and a fluorochemical oxazolidinone composition comprising normally solid, water-insoluble, fluoroaliphatic compounds comprising one or more 2-oxazolidinone moities, ##STR38## at least one of which has a monovalent fluoroaliphatic radical, R.sub.f, which is a fluorinated, stable, inert non-polar, oleophobic, hydrophobic radical having 3 to 20 carbon atoms and 40 to 78 weight percent fluorine and the terminal portion of which has at least three fully fluorinated carbon atoms, bonded to the 5-position carbon atom thereof by an organic linking group, Q.

A process for making an oil and water repellent fiber comprising blending a fluorochemical oxazolidinone composition comprising normally solid, water-insoluble, fluoroaliphatic compounds comprising one or more 2-oxazolidinone moities, ##STR39## at least one of which has a monovalent fluoroaliphatic radical, R.sub.f, which is a fluorinated, stable, inert, non-polar, oleophobic, hydrophobic radical having 3 to 20 carbon atoms and 40 to 78 weight percent fluorine and the terminal portion of which has at least three fully fluorinated carbon atoms, bonded to the 5-position carbon atom thereof by an organic linking group, Q, with a fiber-forming synthetic organic polymer and melt extending said blend to form said fiber.

A process for making a low surface energy film comprising blending a fluorochemical oxazolidinone composition comprising normally solid, water-insoluble, fluoroaliphatic compounds comprising one or more 2-oxazolidinone moities, ##STR40## at least one of which has a monovalent fluoroaliphatic radical, R.sub.f, which is a fluorinated, stable, inert, non-polar, oleophobic, hydrophobic radical having 3 to 20 carbon atoms and 40 to 78 weight percent fluorine and the terminal portion of which has at least three fully fluorinated carbon atoms, bonded to the 5-position carbon atom thereof by an organic linking group, Q, with a film-forming synthetic organic polymer and melt extruding said blend to form said film.
