    Abstract: A fluorinated compound comprising: (i) a fluorochemical oligomeric portion comprising an aliphatic backbone comprising polymerized (meth)acrylate monomeric units, each having a perfluorinated terminal C4-C6 aliphatic group, and an organic residue obtained by removing a hydrogen atom from a functionalized chain transfer agent, wherein: the polymerized (meth)acrylate units are present in a molar ratio of at least 6:1 relative to the functionalized chain transfer agent; and the (meth)acrylate units comprise 0-30 mole-% acrylate units and 70-100 mole-% methacrylate units; (ii) a fluorine-free hydrocarbon moiety; (iii) a di-, tri-, or polymeric isocyanate-derived linking group; and (iv) a group that imparts a durable property when the compound is applied to a fibrous substrate.
