Abstract: POLYURETHANES CONTAINING ISOCYANATE GROUPS ARE REACTED WITH GLYCIDOL TO PREPARE GLYCIDOL-MODIFIED POLYURETHANES USEFUL FOR APPLICATION TO TEXTILE MATERIALS TO IMPROVE THEIR PROPERTIES, E.G., TO IMPART SHRINK RESISTANCE. TYPICAL EXAMPLE: A POLYETHER POLYURETHANE CONTAINING FREE NCO GROUPS IS REACTED WITH GLYCIDOL TO YIELD A GLYCIDOL-MODIFIED POLYMER WHICH IS FORMED INTO AN EMULSION AND APPLIED TO A TEXTILE MATERIAL. THE TREATED TEXTILE MAY BE DIRECTLY CURED OR THE CURING OPERATION MAY BE DELAYED UNTIL THE FABRIC IS MANUFACTURED INTO A FINISHED GARMENT.

Abstract: Novel fluoroalkyl ethers, typically (CF3)2CF-O-CH2-CH2-Br, are prepared by reacting a ketone with an alkali metal fluoride, then reacting the resulting intermediate with a dihaloethane. These ethers may be dehydrohalogenated by reaction with alcoholic KOH to yield the corresponding fluoroalkyl vinyl ethers, e.g., (CF3)2CF-O-CH=CH2. The vinyl derivatives are useful for providing oil- and water-repellent coatings on fibrous materials, e.g., fabrics.

Abstract translation: 通常，通过使酮与碱金属氟化物反应，然后使所得中间体与二卤代乙烷反应制备新的氟代烷基醚（通常为（CF 3）2 CF 2 -O-CH 2 -CH 2 Br）。 这些醚可以通过与醇KOH反应脱卤化氢，得到相应的氟烷基乙烯基醚，例如（CF 3）2 CF-O-CH = CH 2。 乙烯基衍生物可用于在纤维材料（例如织物）上提供防油和防水涂料。

Abstract: Soil-repellent and soil-release properties are imparted to fibrous materials by depositing on them terpolymers of fluoroalkyl allyl (or methallyl) ethers and maleic anhydride, and then curing the treated material at 50*-150* C.

Abstract: Fluorinated ketones are converted into acrylic esters, using the following typical plan: Hexafluoroacetone is reacted with an alkali metal fluoride, and the resulting intermediate is reacted with an omega-halo-aliphatic carboxylic acid ester, yielding an ester of the structure WHEREIN M IS 1-20, R'' is a hydrocarbon group. This ester is reduced to produce an alcohol which is reacted with acryloyl (or methacryloyl) chloride, yielding the product WHEREIN M IS 1-20, R'''' is H or CH3.
