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.
Claims12
A crosslinkable, hydrophilic graft copolymer produced by grafting both (a) a perfluoroacrylate and (b) at least one N-(oxymethyl) acrylamide having the following formula ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 may be the same or different and are a hydrogen atom or a monovalent hydrocarbon radical containing from 1 to about 6 carbon atoms onto poly(oxyalkylene) compositions, which copolymer, upon crosslinking, is hydrophobic and oil repellant.
