Gegenstand der vorliegenden Erfindung sind durch Kalandrieren, Verpressen, Extrudieren, im Spritzgussverfahren hergestellte geformte Gebilde aus Mischpolymerisaten des Vinylchlorids, welche ge@en kochendes Wasser bestndig sind. Sie sind dadurch gekennzeichnet, dass sie aus einem Mischpolymerisat des Vinylchlorids mit 1 bin 15, vorzugsweise 2 bis 12 Gewichtsprozent der Monomeren, einer Verbindung der allgemeinen Formel bestehen, in der R eine starke verzweigte aliphatische oder aromatische Gruppe, h' und R", gleich oder verschieden, ein Atom Wasserstoff, Chlor, Brom oder Fluor, eine CN-Gruppe oder eine C bis C3-Alkylgruppe darstellen. Besonders bevorzugt sind geformte Gebilde aus sochen Mischpolymerisaten, deren Maleinimid-Anteil aus N- (tert. Butyl)-, Isopropyl-, Cyclohexylmaleinimid oder 4-Maleinimidotetraphenylmethan besteht.The present invention relates to shaped structures made from copolymers of vinyl chloride which are resistant to boiling water, produced by calendering, pressing, extruding and injection molding. They are characterized in that they are made from a copolymer of vinyl chloride with 1 to 15, preferably 2 to 12 percent by weight of the monomers, a compound of the general formula in which R is a strongly branched aliphatic or aromatic group, h 'and R ", identical or different, represent an atom of hydrogen, chlorine, bromine or fluorine, a CN group or a C to C3 alkyl group. Shaped ones are particularly preferred Structures of such copolymers, the maleimide part of which consists of N- (tert. Butyl) -, isopropyl-, cyclohexylmaleimide or 4-maleimidotetraphenylmethane.

Die geformten Gebilde können in üblichen Anteilsmengen Filllstoffe, Farbstoffe und organische Stabilisatoren enthalten.The formed structures can be filled in the usual proportions, Contain colorants and organic stabilizers.

Iitr bestimmte Anwendungsgebiete können die geformten Gebilde auch noch in den üblichen Hengen, also 20 bis 40 Gewichtsprozent, bekannte Weichmacher, wie Dioctylphthalat usw., enthalten, denn auch bei solchen Weichmachergehalten zeigen die geformten Gebilde eine höhere Wärmestandfestigkeit als vergleichbare Gebilde aus Polyvinylchlorid oder den bisher bekannten Mischpolymerisaten des Vinylchlorids mit und ohne Gehalt an Weichmachern.The shaped structures can also be used in certain areas of application still in the usual Hengen, i.e. 20 to 40 percent by weight, known plasticizers, such as dioctyl phthalate, etc., because they show even with such plasticizer contents the formed structures have a higher thermal stability than comparable structures made of polyvinyl chloride or the previously known copolymers of vinyl chloride with and without plasticizer content.

Die folgende Tabelle gibt einen Uberlick über die erreichbaren physikalischen Werte von Folien.The following table gives an overview of the achievable physical Values of foils.

Ebenso liegen die Erweichungspunkte der weichgemachten Mischpolymerisate höher als die entsprechenden Vergleichsprodukte mit Normal-PVC. Die Schlagzugzähigkeitswerte der Mischpolymerisatfolien fallen im Vergleich zu Normal-PVC-Folie teilweise etwas niedriger aus, was aber fur bestimmte Anwendungsgebiete kein Nachteil zu sein braucht.The softening points of the plasticized copolymers are also found higher than the corresponding comparable products with normal PVC. The tensile impact strength values of the mixed polymer films sometimes fall somewhat compared to normal PVC film lower, but this need not be a disadvantage for certain areas of application.

Die Reissfestigkeitswerte steigen bei den Mischpolymerisatfolien etwas an gegenüber Normal-PVC, dafUr gehen die Dehnungswerte zurück.The tensile strength values increase somewhat in the case of the mixed polymer films compared to normal PVC, but the elongation values decrease.
