Abstract
The invention provides new fluorine-efficient oil- and water-repellent compositions comprising a fluorochemical oil- and water-repellent agent and a polymer extender comprising at least one percent by weight based on the weight of the extender of interpolymerized units derived from monomers containing at least one blocked or masked isocyanate function.
