Die nach dem erfindungsgemäßen Verfahren erhaltenen Dispersionen zeichnen sich durch eine besonders hohe Stabilität aus. Die Stabilität dieser Emulsionen ist so hoch, daß die Dispersionen beim Eintrocknen unter mechanischer Beanspruchung nicht koagulieren, sondern sich in noch nicht völlig eingetrocknetem Zustand, bevor Filmbildung eingetreten ist, wieder mit Wasser zu einer Dispersion anrühren lassen. Die erfindungsgemäß hergestellten Dispersionen zeigen außer der genannten Eigenschaft der Reemulgierbarkeit eine sehr gute Frost- und Elektrolytbeständigkeit. So tritt z. B. weder beim Abkühlen auf —200C noch bei Zusatz 20%iger Calciumchloridlösungen Koagulation ein. Ebenso hervorragend ist die Verträglichkeit gegenüber Füllstoffen, Pigmenten und anderen Zusätzen, so daß bei der Herstellung von Anstrichmitteln, Klebemitteln oder Imprägniermitteln keine besonderen Vorsichtsmaßnahmen erforderlich sind.The dispersions obtained by the process according to the invention are distinguished by a particularly high stability. The stability of these emulsions is so high that the dispersions do not coagulate when they dry out under mechanical stress, but can be mixed again with water to form a dispersion in a not yet completely dried state before film formation has occurred. In addition to the property of re-emulsifiability mentioned, the dispersions prepared according to the invention show very good resistance to frost and electrolytes. So occurs z. B. neither when cooled to -20 0 C even with the addition of 20% calcium chloride solutions coagulation strength by one. The compatibility with fillers, pigments and other additives is also excellent, so that no special precautionary measures are required in the production of paints, adhesives or impregnating agents.
In dieser Beziehung unterscheiden sich diese Dispersionen von Mischpolymerisaten, die neben den genannten selbstvernetzenden Monomeren kein Acrylamid oder Methacrylamid einpolymerisiert enthalten und/oder die unter Verwendung von vorwiegend ionenaktiven Emulgatoren hergestellt worden sind.In this respect, these dispersions differ from copolymers, which in addition to the self-crosslinking monomers mentioned do not contain any acrylamide or methacrylamide in copolymerized form and / or which have been produced using predominantly ion-active emulsifiers.

Die Mischpolymerisate der erfindungsgemäß erhaltenen Dispersionen besitzen reaktionsfähige Methyloläther- bzw. tertiäre Aminmethylengruppen, die bei erhöhten Temperatüren und/oder unter Einwirkung von sauren Katalysatoren gespalten werden und gleichzeitig eine Selbstvernetzung der Mischpolymerisate unter Bildung von unlöslichen Vernetzungsprodukten bewirken. Auf Grund ihrer Eigenschaft, bereits unter milden Bedingungen in unlösliche Vernetzungsprodukte überzugehen, können die genannten Polymerisate zur Herstellung von beliebig geformten Gebilden, wie Überzügen, Imprägnierungen und Verklebungen, herangezogen werden.The copolymers of the dispersions obtained according to the invention have reactive methylol ether or tertiary amine methylene groups, which at elevated temperatures and / or under the action are cleaved by acidic catalysts and at the same time self-crosslinking of the copolymers cause with the formation of insoluble crosslinking products. Due to their property, already under The polymers mentioned can convert into insoluble crosslinking products under mild conditions for the production of structures of any shape, such as coatings, impregnations and bonds, can be used.
Aus der französischen Patentschrift 1127 727 ist bereits bekannt, Methyloläther des Acrylamids zusammen mit Acrylamid in wäßriger Emulsion in Gegenwart von ionischen Emulgatoren zu polymerisieren. From French patent specification 1127 727 it is already known to combine methylol ethers of acrylamide polymerize with acrylamide in an aqueous emulsion in the presence of ionic emulsifiers.

In ein Polymerisationsgefäß aus Glas, ausgestattet mit Rührer und Thermometer, wird eine Lösung aus 5 Gewichtsteilen eines Emulgators bzw. eines Emulgatorgemisches in 130 Gewichtsteilen Wasser gegeben. Zu dieser Lösung werden dann zunächst die wasserlöslichen Monomeren, dann die wasserunlöslichen Monomeren gegeben. Nachdem unter Rühren mit Stickstoff gespült wurde, wird auf 500C erhitzt und die Polymerisation durch Zusatz von je 0,4 Gewichtsteilen Natriummetabisulfit und Kaliumpersulfat in je 10 Gewichtsteilen Wasser gestartet. Durch mäßige Außenkühlung wird die Temperatur des Gemisches auf 5O0C gehalten. Nach etwa 10 Stunden ist die Polymerisation praktisch beendet. Der pH-Wert beträgt etwa 3 und wird durch Zusatz von Ammoniak auf 6 bis 7 eingestellt.A solution of 5 parts by weight of an emulsifier or an emulsifier mixture in 130 parts by weight of water is placed in a glass polymerization vessel equipped with a stirrer and thermometer. First the water-soluble monomers, then the water-insoluble monomers, are then added to this solution. After flushing with nitrogen while stirring, the mixture is heated to 50 ° C. and the polymerization is started by adding 0.4 parts by weight of sodium metabisulfite and potassium persulfate each in 10 parts by weight of water. By moderate external cooling the temperature of the mixture is maintained at 5O 0 C. The polymerization is practically complete after about 10 hours. The pH is about 3 and is adjusted to 6 to 7 by adding ammonia.
Als nichtionischer Emulgator wurde ein Umsetzungsprodukt aus 1 Mol ölsäure mit etwa 15 Mol Äthylenoxyd verwendet, während als anionischer Emulgator das Natriumsalz eines langkettigen, d. h. etwa 12 bis 16 Kohlenstoffe enthaltenden Alkylsulfonate eingesetzt wurde.A reaction product of 1 mole of oleic acid with about 15 moles of ethylene oxide was used as a nonionic emulsifier used, while the sodium salt of a long-chain, d. H. about 12 to 16 carbon-containing alkyl sulfonates was used.
Das Ergebnis der Nacharbeitung des Beispiels 4 der USA.-Patentschrift 2 595 907 ist in der nachfolgenden Tabelle unter X angegeben. Auch bei Zusatz von 10,5 Gewichtsteilen an Emulgator (Natriumsalz eines Alkylsulfats mit 16 C-Atomen) und Einhalten eines pH-Wertes von 5,2 fiel das Copolymerisat langsam aus.The result of reworking Example 4 of U.S. Patent 2,595,907 is as follows Table indicated under X. Even with the addition of 10.5 parts by weight of emulsifier (sodium salt an alkyl sulfate with 16 carbon atoms) and maintaining a pH value of 5.2, the copolymer fell slowly out.
