ABSTRACT:
Fluoroalkyl-substituted maleic anhydride polymers, substrates treated therewith, and to novel processes for preparing and using the same. The polymers can be prepared by reacting: (1) terminally unsaturated alkenylamines or alcohols (e.g. allyl amine or alcohol, or diallyl amine) with maleic anhydride polymers, and (2) the resulting polymeric amides or esters with fluoroalkyl iodides in the presence of a free radical initiator. Dehydroiodination of the resulting product with base yields novel polymeric products which provide oil- and water-repellency as well as soil-resistance when applied to substrates, particularly nylon fibers.
