Abstract
Abstract 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.
