Description

Grundlage für Zitzenstifte Zusatz zum Patent 735 177 In dem Patent 735 177 sind Zitzenstifte besch,rieben, deren Grundluge aus hydrophilen, jedoch in Wasser nur quellbaren Mischpoly; merisaten als Vinylverbindungen und a, ß-ungesättigten Dicarbonsäuren oder deren Abkömmlingen oder aus Abkömmlingen dieser Mischpolymerisate besteht.Basis for teat pins Addition to patent 735 177 In the patent 735 177 are teat sticks, rubbed, whose base consists of hydrophilic, however mixed poly which is only swellable in water; merisates as vinyl compounds and α, ß-unsaturated Dicarboxylic acids or their derivatives or from derivatives of these copolymers consists.

Es wurde nun gefunden, daß nicht nur die genannten Erzeugnisse, sondern in gleicher Weise auch andere hydrophile, in Wasser quellbare, aber nicht lösliche hochpolymere Körper als Grundlage für Zitzenstifte geeignet sind. Die Hydrophilie derartiger Körper kann z. B. auf der Anwesenheit von Hydroxyl-, Carboxyl- oder Aminogruppen beruhen, wie sie im Vinylalkohol, der Acrylsäure oder dem Acrylamid vorliegen, doch muß deren Anzahl im Gesamtmolekül gegenüber hydrophoben, also im Wasser unlöslich machenden Gruppen derart abgestimmt sein, daß der gesamte Körper nicht in Wasser löslich, sondern nur quellbar ist. It has now been found that not only the products mentioned, but in the same way also other hydrophilic, water-swellable but insoluble high polymer bodies are suitable as a basis for teat sticks. The hydrophilicity such a body can, for. B. on the presence of hydroxyl, carboxyl or amino groups based, as they are in vinyl alcohol, acrylic acid or acrylamide, but The number of these in the overall molecule must be compared to hydrophobic ones, i.e. insoluble in water making groups should be coordinated in such a way that the entire body is not soluble in water, but only swellable.

Als Beispiele seien genannt: teilweise veresterter oder acetalisierter Polyvinylalkohol, teilweise verseiftes Polyvinylacetat, ferner das Verseifungsprodukt eines Mischpolymerisates eines verseifharen Vinylesters, wie Vinylacetat. mit einem in das Polymolekül eingebauten, unter gleichen Umsetzungsbedingungen unverseifbaren Bestandteil, wie z. B. Examples include: partially esterified or acetalized Polyvinyl alcohol, partially saponified polyvinyl acetate, and also the saponification product a copolymer of a saponifiable vinyl ester, such as vinyl acetate. with a built into the polymolecule, unsaponifiable under the same reaction conditions Component, such as B.

Vinylbenzoat, Crotonsäureester oder Vinylchlorid, schließlich das Produkt der direkten NIischpolymerisation eines hydrophilen und eines hydrophoben Bestandteils, wie Acrylsäureamid und Acrylsäureester oder Crotonsäure und Vinylester.Vinyl benzoate, crotonic acid ester or vinyl chloride, finally that Product of the direct copolymerization of one hydrophilic and one hydrophobic Component such as acrylic acid amide and acrylic acid ester or crotonic acid and vinyl ester.

Bei der Bereitung von Zitzenstiften aus den angeführten Stoffen erwiesen sich Zusätze von Hilfsmitteln, wie z. R. Weichmachern, oft als vorteilhaft. Proven in the preparation of teat sticks from the substances listed additions of auxiliaries, such as. R. Plasticizers, often considered beneficial.

Ferner kann man der Masse Arzneistoffe zusetzen, wie sie zur Behandlung von Entzündungen und Strikturen des Zitzenkanals der Kühe geeignet sind, so z. B. desinfizierende oder chemotherapeutisch wirksame Mittel. Medicines can also be added to the mass, as they are for treatment inflammations and strictures of the teat canal of the cows are suitable, e.g. B. disinfectant or chemotherapeutic agents.

Das folgende Ausführungsbeispiel veranschaulicht die Herstellung von Zitzenstiften unter Verwendung der vorgenannten hochpolymeren Körper. The following exemplary embodiment illustrates the production of teat sticks using the aforesaid high polymer bodies.

Beispiel Durch saure Verseifung eines Mischpolymerisates aus Vinylacetat und Vinylbenzoat gewonnenes wasserquellbares hochmolekulares Polymerisationsprodukt . 52 Gewichtsteile Glycerin ................ 8 -Bis - 2 - methyl - 4 - aminochinolyl - 6 - carbamid -hydrochlorid .......... 0,4 Destilliertes Wasser .... 39.6 -Ioo,o Gewichtsteile Die Zitzenstifte werden wie folgt hergestellt: Das Bis-2-methyl-4-aminochinolyl-6-carhamidhydrochlorid wird in dem Wasser gelöst. Die Lösung wird mit dem Polymerisat und dem Glycerin in einem Knetwerk gründlich verknetet. Die Masse wird anschließend in eine für die Kunststoffverarbeitung gebräuchliche Spritzpresse gefüllt, hierin bis zur Erreichung einer homogenen weichplastischen Beschaffenheit erhitzt und als 2 3 mm dicker Strang herausgedrückt. L)er austretende heiße Strang wird von Zeit zu Zeit abgeschnitten. Die so erhaltenen Schnüre läßt man erkalten, hängt sie gegebenenfalls einige Zeit zum Naditrocknen auf und stellt aus ihnen vorn etwas zugespitzte, hinten plattgedrückte Stifte von etwa 6 cm Länge her. Example By acidic saponification of a copolymer made from vinyl acetate and vinyl benzoate obtained water-swellable high molecular weight polymerization product . 52 parts by weight of glycerine ................ 8 -Bis - 2 - methyl - 4 - aminoquinolyl - 6 - carbamide hydrochloride .......... 0.4 distilled water .... 39.6 -Ioo, o Parts by weight The teat sticks are manufactured as follows: The bis-2-methyl-4-aminoquinolyl-6-carhamide hydrochloride is dissolved in the water. The solution is with the polymer and the glycerin kneaded thoroughly in a kneading machine. The mass is then converted into one for the Plastics processing customary injection press filled, here up to the achievement a homogeneous, soft plastic texture and heated as a 2 3 mm thick strand pushed out. L) the emerging hot strand is cut off from time to time. The cords obtained in this way are allowed to cool, if necessary they hang for a while to dry the nadis and make them somewhat pointed at the front and flattened at the back Pins about 6 cm long.
