Abstract: A sealing device for electrical plug connectors is configured in such a way that a favorable, cost-saving and functionally safe production of plug connectors, from a manufacturing point of view, is fulfilled. The plug connectors each have a contact carrier in a plug housing. Contact carrier is penetrated by accommodation chambers, which with one end each open out into one tub-shaped installation space of plug connector. These ends are covered by a restraining element, so that a sealing compound, which is free-flowing, curable and inserted into installation space, which is able to completely seal against contact elements that have been plugged through it, remains in the installation space. The sealing device for electrical plug connectors is provided especially for use in the automobile industry.

Abstract: This invention pertains to a polyester composition containing finely divided polymer particles in a substantially homodisperse distribution. The polymer particles are prepared in an emulsion-polymerization process and are crosslinked.The polymer particles exhibit an extremely narrow grain-size distribution and are incorporated into the polyester during the synthesis thereof.The invention also relates to films, particularly stretched films, which are produced from the polyester composition and which can also be used as base films for the production of composite films.It is additionally also possible to produce filaments and fibers from the composition according to the invention or with the addition of this composition to other polymers.The films are preferably used as bases for magnetic recording elements or for capacitors, and fiber or filaments are employed in the production of tire cord.
