    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 percent, 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.

    Abstract translation: 可以通过在树脂中加入少量约1％的具有从有机基团悬挂的具有一至四个氟烷基的两亲化合物来改善合成树脂的挤出长丝的污垢和防污性。 疏水性由氟烷基提供，氟烷基倾向于在纤维的表面集中。

    Abstract: NOVEL FLUOROPERHALODIAZOLEFINE ARE PREPARED BY REACTING A FLUOROPERHALOALKYLIDENE IMINE WITH A FLUOROPERHALOAZAOLEFIN IN AN APROTIC, POLAR LIQUID REACTION MEDIUM IN THE PRESENCE OF AN IONIZABLE FLUORIDE SALT. FOR EXAMPLE, PERFLUORO-2,4,4,6-TETRAMETHYL-3,5-DIAZA -25-HEPTADIENE IS PREPARED BY REACTING HEXAFLUOROISOPROYLIDENE IMINE WITH PERFLUORO-2,4-DIMETHYL-3-AZA-2-PENTENE IN ACETONITRILE IN THE PRESENCE OF POTASSIUM FLUORIDE. THE FLUOROPERHALODIAZAOLEFINS ARE USEFUL AS LIQUID DIELECTRICS AND AS INTERMEDIATES IN THE PREPARATION OF P OTHER FLUORINATED ORGANIC COMPOUNDS.
