    摘要： Fibrous substrates are durably modified by applying a polyoxyethylene-containing silane to the substrate and heating the substrate to cure the silane. Durability of the treatment is achieved by using a silane having the formula R(OCH.sub.2 CH.sub.2).sub.x OR'SR"SiZ.sub.3 where Z denotes a hydroxyl or a hydrolyzable radical, R' and R" are divalent aliphatic radicals of suitable size, R is hydrogen, lower alkyl or lower acyl and x has a value of at least 3. The silane is applied to the fibrous substrate, such as a hydrophobic fabric, as a homogeneous liquid composition comprising the silane, a volatile liquid carrier and a siloxane polymerization catalyst to provide a treated substrate having improved properties, such as hydrophilicity.

    摘要： Fluorinated condensation polymers which are made up of a combination of Blocks I and II: ##STR1## In these structures R.sub.f is a branched or linear perfluoroalkyl or perfluorooxaalkyl group of 5-18 carbons,R.sup.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.sup.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, andp 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.
