Abstract: FLUOROPERHALOALKYLIDENE IMINES HAVING THE FORMULA Y1Y2C=NH, WHEREIN Y1 AND Y2 ARE FLUORINE OR FLUOROPERHALOALKYL RADICALS, ARE PREPARED BY HYDROLYZING THE CORRESPONDING FLUOROPERHALOALKYL ISOCYANATE HAVING THE FORMULA Y1Y2FCNCO WITH WATER IN THE FORM OF A HYDRATE SUCH AS HEXAFLUOROACETONE MONOHYDRATE. THE FLUOROPERHALOALKYLIDENE IMINES ARE USEFUL AS INTERMEDIATES IN THE PREPARATION OF OTHER FLUORINATED COMPOUNDS.

Abstract: THE SOIL AND STAIN REPELLENCY OF EXTRUDED FILAMENTS OF A SYNTHETIC RESIN CAN BE IMPROVED BY INCORPORATING IN THE RESIN A SMALL AMOUNT, ABOUT 1%, OF AN AMPHIPATHIC COMPOUND HAVING FROM ONE TO FOUR FLUOROALKYL GROUPS PENDENT FROM AN ORGANIC RADICAL. THE REPELLENCY IS PROVIDED BY THE FLUOROALKYL GROUPS, WHICH TEND TO BE CONCENTRATED AT THE SURFACE OF THE FIBER.
