Abstract
Abstract Fluorinated condensation polymers which are made up of a combination of Blocks I and II: ##STR1## In these structures R f is a branched or linear perfluoroalkyl or perfluorooxaalkyl group of 5-18 carbons, R 3 is an aliphatic triradical of 2-50 carbon atoms selected from the group consisting of branched or straight chain alkylene, alkylenethioalkylene, alkyleneoxyalkylene and alkyleneiminoalkylene, R 4 is hydrogen or methyl, D is the organic divalent radial of a diisocyanate, k is 8-100, m is an integer of 1 to 5, n is 1 or 2, and p is an integer of 1 to 5, Wherein Blocks I and II are combined in a ratio of at least about 15% to 70% by weight of Block I to 30% to 85% by weight of Block II. The blocks as defined are connected by urea linkages in the final product condensate. The polymer condensates of this invention are useful as coatings on textiles, glass, linoleum, leather, wood, tile, metals, plastics, and various materials. They are of particular use on textile materials as soil release agents, showing increased durability as compared to urethane-connected condensation block polymers.
