Abstract
A graft copolymer is produced by grafting both at least one perfluoroacrylate and at least one N-(oxymethyl)acrylamide, e.g., IBMA, onto a poly(oxyalkylene) composition. This graft copolymer is water dispersible prior to crosslinking while after crosslinking, it becomes a highly durable hydrophobic and oil repellent coating for fibers, textiles, and the like.
