Abstract
The present invention is directed to a water- and oil repellency-imparting preparation for fibrous and other substrates, the preparation comprising a fluorinated polymer and a tacking monomer, oligomer or polymer containing at least one anhydride functional group or a group capable of forming an anhydride functional group, optionally together with an anhydride-forming catalyst, such as sodium hypophosphite. The preparation can further optionally comprise other additives such as, for example, an extender; a softener; an antioxidant; a surfactant; and/or a plasticizer.
