Description

Weichmacher für Polyvinylchlorid und dessen Mischpolymerisate Hochmolekulare Verbindungen, wie Polyvinylchlorid oder dessen Mischpolymerisate, werden in ihren Eigenschaften verbessert, wenn man ihnen gemischt aJiphatisch-aromatische bzw. =hydroaromatische Ketone als Weichmacher einverleibt. Während der aliphatische Rest dieser Mischketone mehr als q. Kohlenstoffatome enthalten soll, kann der aromatische Rest die verschiedensten Substituenten, wie z. B. Halogen, Alkyl usw., beätzen. Die z. B. durch Kondensation von höheren Fettsäurechlo-riden mit Kohbenwasserstoffen erhältlichen Mischketone verleihen den mit ihnen behandelten Polyvinylchlorid @enthaltenden hochpolymeren Verbindungen eine gute Dehnbarkeit und Kältebeständigkeit. Es sind hier beispielsweise zu nennen das Laurochlornaphthalm, Isoheptanoylchlornaphthalin, Isooctanoylchlomaphthalin, Butyrochlornaphthalin, Stearochlorbenzgj, NaphthenoyInaphthylketon, Nonanoylp'henon, Methyllaurophenon, Laurotetrahydronaphthalin usw. Es können auch beliebige Gemische solcher Ketone angewendet werden; insbesondere läßt sich damit durch geeignete Mischungen ein Auskrsstallisieren aus solchen Hochpolymeren verhindern, in denen die Ketone schwerer löslich sind. Die Löslichkeit kann auch häufig durch Zusatz geringer Mengen anderer bekannter Weichmacher verbessert werden.Plasticizer for polyvinyl chloride and its copolymers, high molecular weight Compounds such as polyvinyl chloride or its copolymers are used in their Properties are improved if they are mixed with aJiphatic-aromatic or hydroaromatic Incorporated ketones as plasticizers. While the aliphatic remainder of these mixed ketones more than q. Should contain carbon atoms, the aromatic radical can be the most varied Substituents such as B. halogen, alkyl, etc., etch. The z. B. by condensation mixed ketones obtainable from higher fatty acid chlorides with hydrocarbons give the treated with them polyvinyl chloride @containing high polymers Connections have good ductility and resistance to cold. There are for example here to mention the laurochloronaphthalene, isoheptanoylchloronaphthalene, isooctanoylchlomaphthalene, Butyrochloronaphthalene, Stearochlorbenzgj, NaphthenoyInaphthylketon, Nonanoylphenon, Methyllaurophenone, laurotetrahydronaphthalene, etc. Any mixtures can also be used such ketones are used; In particular, it can be used with suitable mixtures Prevent Auskrsstallisiert from those high polymers in which the ketones are more difficult to dissolve. The solubility can also often be increased by adding small amounts other known plasticizers can be improved.

Beispiel t Polyvinylchlorid oder ein Mischpolymerisat aus Polyvinylchlorid und Acrylsäuremethylester wird mit 20 bis 40% Lauro-a-chlornaphthaän bei geeigneten Temperaturen verwalzt. Die erhaltenen Felle zeichnen sich durch große Dehnung und Kältebeständigkeit aüs. Solche aus Polyvinylchlorid mit 4o% Laurochlornaphthalin sind von gunuuiartiger Beschaffenheit. Der Gewichtsverlust eines solchen Felles beträgt bei 7o° nach 8 Tagen nur o,2%. Bei -2o° ist dieses Fell noch sehr weich. ' Beispiel 2 Polyvi'nylchlorid' oder ein Mischpolymeri= sat aus Polyvinylchlorid und Acrylsäureäthylester wird mit 2o bis 400/0 einer Mischung von 9o Teilen Lauronaphthalin und i o Teilen Undecanoylchlornaphthalin bei Temperaturen von ioo bis 16o' verwalzt. Die Felle haben die zuvor beschriebenen Eigenschaften, zeigen aber auch bei langem Aufbewahren bei tiefer Temperatur kein Auskristallisieren des Weichmachers.Example t polyvinyl chloride or a copolymer of polyvinyl chloride and methyl acrylate is used with 20 to 40% lauro-a-chloronaphthaene when appropriate Temperatures rolled. The skins obtained are characterized by great elongation and Cold resistance aüs. Those made of polyvinyl chloride with 40% laurochloronaphthalene are of a gunuui-like texture. The weight loss of such a fur at 70 ° after 8 days is only 0.2%. At -2o ° this fur is still very soft. 'Example 2 Polyvinyl chloride' or a mixed polymer of polyvinyl chloride and ethyl acrylate is with 2o to 400/0 a mixture of 90 parts of lauronaphthalene and 10 parts of undecanoylchloronaphthalene at temperatures rolled from ioo to 16o '. The skins have the properties described above, but do not show any crystallization even after long periods of storage at low temperatures of the plasticizer.
