Polyacrylsäureamid, welches durch Polymerisation in wäßriger Lösung hergestellt worden ist, bildet wie die ebenso hergestellten Mischpolymerisate mit Methacrylsäureamid mit den üblichen Hydrophobiermitteln auf der Grundlage von Metallsalzen, z. B. Aluminium- oder Zirkonsalzen und Paraffinen, irreversible Niederschläge. Es war aus diesem Grund bisher nicht möglich, Textilien mit einer Kombination beider Hilfsmittel in einem Bad zu behandeln.Polyacrylic acid amide, which has been prepared by polymerization in aqueous solution, forms like the copolymers with methacrylic acid amide produced in the same way with the usual water repellants based on metal salts, e.g. B. aluminum or zirconium salts and paraffins, irreversible precipitation. For this reason, it was previously not possible to use textiles with a combination treat both aids in one bath.
Man hat deshalb zur Veredlung von Textilien mit derartigen Kombinationen in wäßriger Lösung hergestellte Mischpolymerisate des Methacrylsäureamids mit Estern ungesättigter Carbonsäuren, ζ. Β. Acrylsäureäthylester und Methacrylsäureäthylester, oder mit basischen Monomeren, wie Vinylimidazol, verwendet.One has therefore produced for the finishing of textiles with such combinations in aqueous solution Copolymers of methacrylic acid amide with esters of unsaturated carboxylic acids, ζ. Β. Acrylic acid ethyl ester and methacrylic acid ethyl ester, or with basic monomers such as vinylimidazole, used.
Bei dieser Methode müssen allerdings wieder andere Nachteile in Kauf genommen werden. Der Zusatz von Acrylsäureestern vermindert die Anzahl der reaktionsfähigen Gruppen im Mischpolymerisat und damit die Möglichkeit einer durchgreifenden Vernetzung mit reaktionsfähigen Kondensaten des Harnstoffs und Melamins oder ähnlichen Verbindungen des Formaldehyds.With this method, however, other disadvantages have to be accepted. Of the The addition of acrylic acid esters reduces the number of reactive groups in the copolymer and thus the possibility of thorough networking with reactive condensates of the Urea and melamine or similar compounds of formaldehyde.
Das führt aber in Verbindung mit dem ohnehin plastischeren Verhalten, bewirkt durch die Esterkomponente, dazu, daß ζ. B. die Steifheit nachläßt, was sich speziell in Verbindung mit paraffinhaltigen Hydrophobiermitteln auswirkt und für viele Appreturzwecke, bei denen es gerade auf einen steifen Griff ankommt, nachteilig ist.In connection with the already more plastic behavior, caused by the ester component, this leads to to the fact that ζ. B. the stiffness decreases, which is especially in connection with paraffin-containing Water repellants have an effect and for many finishing purposes where it is just on a stiff Grip matters, is disadvantageous.
Es ist zwar ein Verfahren zur Herstellung von hydrophobiermittelverträglichen Mischpolymerisaten bekannt, die nur Acrylsäureamid und Methacrylsäureamid einpolymerisiert enthalten. Man polymerisiert hierzu Acrylsäureamid und Methacrylsäureamid in Glykoläthern und erhält die Mischpolymerisate als Pulver, die im Reaktionsmedium unlöslich sind. Die Befreiung dieser Mischpolymerisate von anhaftendem Glykoläther durch Zentrifugieren, Nachwaschen mit Methanol und Trocknen, mit dem schließlichen Endzweck, sie wiederum in Wasser bei der Verwendung aufzulösen, ist äußerst umständlich.It is a process for the production of copolymers compatible with hydrophobizing agents known that contain only acrylic acid amide and methacrylic acid amide polymerized. One polymerizes this acrylic acid amide and methacrylic acid amide in glycol ethers and receives the copolymers as Powders that are insoluble in the reaction medium. The liberation of these copolymers from adhering Glycol ethers by centrifugation, rewashing with methanol and drying, with the ultimate end use, To dissolve them again in water when using them is extremely cumbersome.
Es wurde nun gefunden, daß solche flockenstabile Mischungen aus Polyacrylamidlösungen und wäßrigen
Dispersionen von Hydrophiermitteln, die Polyacrylamid enthalten, das durch Polymerisation von
99 % und mehr Acrylsäureamid und 0 bis 1 °/o anderer Monomeren, jeweils bezogen auf das Endpolymerisat,

zum Ausrüsten von TextilienIt has now been found that such flake-stable mixtures of polyacrylamide solutions and aqueous dispersions of water repellants containing polyacrylamide are formed by polymerizing 99% and more of acrylic acid amide and 0 to 1% of other monomers, based on the final polymer, in the presence of radical formers and mercaptans which have an oxygen-containing group in the vicinity of the sulfhydryl group, use of mixtures which are stable to flocculation

as Die Herstellung des Polyacrylsäureamids wird in an sich bekannter Weise vorgenommen. Man polymerisiert Acrylsäureamid in wäßriger Lösung bei Temperaturen, die zweckmäßig zwischen 10 und 100° C liegen und vorzugsweise bei pH-Werten zwischen 3,5 bis 6. Wesentlich ist jedoch, daß bei der Polymerisation des Acrylsäureamids Radikalbildner und Mercaptane, die in Nachbarschaft zur Sulfhydrylgruppe eine Sauerstoff enthaltende Gruppe tragen, anwesend sind. Geeignete Radikalbildner sind insbesondere Wasserstoffperoxyd, Acetylperoxyd oder Azoverbindungen, wie z. B. Azodiisobuttersäurenitril. Weniger geeignet sind Salze der Perschwefelsäure und Perborate. Geeignete Mercaptane, die in dem Aktivatorsystem verwendet werden können, sind insbesondere Mercaptoäthanol, 1-Thioglycerin oder Thioglykolsäure.as The production of polyacrylic acid amide is described in made in a known manner. Acrylic acid amide is polymerized in an aqueous solution Temperatures which are expediently between 10 and 100 ° C. and preferably at pH values between 3.5 and 6. It is essential, however, that radical formers are used in the polymerization of the acrylic acid amide and mercaptans which have an oxygen-containing group adjacent to the sulfhydryl group wear, are present. Suitable radical formers are, in particular, hydrogen peroxide and acetyl peroxide or azo compounds, such as. B. azodiisobutyric acid nitrile. Salts of persulphuric acid are less suitable and perborate. Suitable mercaptans that can be used in the activator system, are in particular mercaptoethanol, 1-thioglycerol or thioglycolic acid.
Neben Acrylamid können sehr geringe Mengen an anderen Monomeren am Aufbau des Acrylamidpolymerisats beteiligt sein: beispielsweise Carboxylgruppen enthaltende Monomere; deren Anteil beträgt jedoch nicht mehr als 1%, bezogen auf das Endpolymerisat. Wenn im folgenden von Polyacrylsäureamid gesprochen wird, so sind darunter auch solche Mischpolymerisate des Acrylsäureamids, die zu 99% und mehr aus Acrylsäureamid aufgebaut sind, zu verstehen. Für die Herstellung des Polyacrylsäureamids wird kein Schutz begehrt.In addition to acrylamide, very small amounts of other monomers can build up the acrylamide polymer be involved: for example monomers containing carboxyl groups; whose share is but not more than 1%, based on the final polymer. If in the following from polyacrylamide is spoken, so among them are copolymers of acrylic acid amide that 99% and more of acrylic acid amide are to be understood. For the production of the polyacrylic acid amide no protection is sought.
