BIe Erfindung besieht sieh auf eine Liisohung polymerer Werkstoffe.The invention relates to a solution of polymeric materials Materials.

Mischungen aae polymtren Substanzen finden seit langem ausgedehnte Anwendung in der Industrie der Lacke und Anstrichmittel sowie in der Klebstoffteohnologie. In neuerer Zeit haben Kombinationen von polymeres Werkstoffen dann auoh Bedeutung für die Entwicklung bestimmter physikalischtechnologischer Eigenschaften gewonnen und so dazu beigetragen, daß sioh die Anwendungsbereiche der Plastformstoffe erweitern konnten. Trgtz dieser bereits reoht beachtlichen Bedeutung solcher mindestens binärer Systeme hochpolymerer Substanzen liegen noch relativ wenig Erfahrungen über die physikalisch-chemischen Gesetzmäßigkeiten im Bereich derartiger Kombinationen vor· Demgemäß finden sich auoh noch nicht einheitliche Auffassungen zum Begriffsinhalt der Korobinierbarkeit und der Verträglichkeit der Polymeren untereinander, leider resultiert daraus auoh eine gewisse Unsicherheit in der Beurteilung gewerblich verwendbarer technologischer Effekte derartiger Liisohungen von Polymeren.Mixtures of polymeric substances have been found for a long time Extensive application in the lacquer and paint industry as well as in the adhesive industry. In more recent Combinations of polymer materials then have time Also gained importance for the development of certain physical-technological properties and thus contributed to the fact that sioh could expand the areas of application of plastic materials. Despite the already considerable importance of such at least binary systems of high-polymer substances, there is still relatively little experience the physico-chemical laws in the area of such combinations are found accordingly Opinions on the conceptual content of the compatibility and compatibility of the polymers with one another are not yet uniform, unfortunately this also results in a certain uncertainty in the assessment of commercially usable technological effects of such solutions of polymers.

Zweck der vorliegenden Erfindung ist es, weitere solcher Systeme hinsiohtlioh ihrer technologischen Verwertbarkeit im Gebiet der Laok- oder Klebstofftechnologie bzw. in der Anwendung als Plaetforiastoffe eu finden. Die Aufgabe bestand darin» hierzu polare Pclymere zu verwenden, deren Polarität duroh konstitutionell verschiedenartige Atome bzw. Atomgruppierungen bedingt 1st.The purpose of the present invention is to provide further such Systems in terms of their technological usability in the Find the area of Laok or glue technology or in the application as Plaetforiastoffe eu. The task existed to use polar polymers for this purpose, their polarity Due to the constitutionally different atoms or atom groupings, 1st.

Mischpolymerisaten dieser Sster untereinander andererseits su kombinieren und au transparenten Formstoffen, insbesondere Folien, au verformen. Unter den Polymerisationsprodukten des Vinylchlorlds mit dem angegebenen Gehalt an Chlor sollen Homopolymerisate des Vinylchlorids, vornehmlich hergestellt durch Suspensionspolymerisation, dessen Naohehlorlerungsprodukte mit 60 bis 67 # Cl, sowie die Mischpolymerisate des Vinylchlorids mit Vinylacetat mit maximal ea. 40 £ Vinylacetatgehalt oder dem äquivalenten Anteil an Acrylsäureester der aliphatischen C-1 bis C. Alkohole verstanden werden. Sie zweitens zur Kombination mit einem dieser Polymerisationsprodukte erfindungsgemäß zu verwendenden Komponenten der neuartigen Polymerenmischung ist ein Homopolymerisat aus dem Aerylsäureättylester oder aus dem Methacrylsäuremethylester oder ein Mischpolymerisat aus Methacrylsäureestern C^ bis C. und Ä'thylacrylat und analoger Zusammensetzung.On the other hand, copolymers of these systems can be combined with one another and shaped from transparent molding materials, in particular films. Among the polymerization products of vinyl chloride with the specified chlorine content, homopolymers of vinyl chloride, primarily produced by suspension polymerization, its Naohlorlerungsprodukte with 60 to 67 # Cl, and the copolymers of vinyl chloride with vinyl acetate with a maximum of about 40 £ vinyl acetate content or the equivalent proportion of acrylic acid ester the aliphatic C -1 to C. alcohols are understood. Secondly, for the combination with one of these polymerization products to be used according to the invention components of the novel polymer mixture is a homopolymer of the arylate or of the methyl methacrylate or a copolymer of methacrylic esters C ^ to C and ethyl acrylate and an analogous composition.

Sie Kombination dieser Komponenten zu einem erfindungsgemäßen transparent und homogen aussehenden Forrastoff, vor-. nehmlich einem Film', Folie oder Spriteguß-Formstoff oder Extrusionsprof11, kann entweder gemäß der bekannten Regeln der thermoplastischen Verarbeitung geschehen. Darüber hinaus ist es aber auch gelungen, derartige Kombinationen über eine gemeinsame Auflösung der Komponenten herzustellen, UEa aus ihnen transparente und homogen aussehende Filme, Laokschichten, Klebstoffschiohten und ähnliches zu erhalten. Es ist als ein weiterer Inhalt unserer ürfindung o au betrachten, daß dieser zweite Weg der Kombination der ~ beanspruchten Komponenten über eine homogene flüssige -* Phase an spezielle Lösungsmittel gebunden ist. Hier sind -*-» je naoh der spezifischen Zusammensetzung der Komponenten -j fUr die Kombination auoh verschieden konstituierte Lö-J^ sungsmittel erforderlich. Wir pennen hier Äthylaoetat, Benaylaoetat, Aoeton, Dimethylformamid, Brombenzol. Von diesen kommt, wie wir finden konnten, dem Äthylacetat die Fähigkeit au, fur jede <±tv sich ergebenden typischen Kombinationen als Lösungsmittel für homogene Lösungen undYou combination of these components to form a transparent and homogeneous-looking molding material according to the invention. namely a film, foil or injection molding material or extrusion profile, can either be done according to the known rules of thermoplastic processing. In addition, however, it has also been possible to produce such combinations by jointly dissolving the components, to obtain transparent and homogeneous-looking films, Laok layers, adhesive layers and the like from them. It is also to be regarded as a further content of our invention that this second way of combining the claimed components is bound to special solvents via a homogeneous liquid phase. Here, depending on the specific composition of the components, differently constituted solvents are required for the combination. We sleep here ethyl acetate, benay acetate, aoeton, dimethylformamide, bromobenzene. From these, as we have been able to find, comes the ability of ethyl acetate to act as a solvent for homogeneous solutions and for every typical combination that results

Bei der Ermittlung physikalischer Eigenschaften derartiger Folien oder Filme hat sieh weiterhin die überraschende, nicht voraussehbare Feststellung ergehen, daß die !Reißfestigkeit der Mischfilz aus den erfindungsgemäßen Komponenten unabhängig von ihrer Herstellungsart, meist bei einem Mischungsverhältnis 1 : 1 (Gw.)', einen Maximalwert oberhalb der Reißfestigkeiten der in gleicher Weise hergestellten Koraponentenfilme aufweist.When determining the physical properties of such foils or films, the surprising Unpredictable finding was made that the tear strength of the mixed felt from the inventive Components regardless of their production method, usually with a mixing ratio of 1: 1 (weight) ', one Maximum value above the tear strengths of the same Has produced coraponent films.

Beispielsweise stellten wir beim transparenten homogenen Uisohfllm aus naohchloriertem Polyvinylchlorid mit ca. 62 # CJ. und Polymethacrylat ("1 J 1), aus der Lösung von Bssigeater gegossen, eine Reißfestigkeit von 750 kp/om fest, gegenüber den Werten bei den beiden Komponenten von 580 kp/om2 bsw. 450 kp/cm .For example, in the case of the transparent, homogeneous Uisohfllm made of chlorinated polyvinyl chloride with approx. 62 # CJ. and polymethacrylate ("1 J 1), cast from the solution of Bssigeater, a tensile strength of 750 kp / om solid, compared to the values for the two components of 580 kp / om 2 or 450 kp / cm.

Für den auf gleichem i/ege erhaltenen transparenten Mischfilm aus einem Mischpolymerisat aus Vinylchlorid + Vinylacetat ca. 60 ; 40 einerseits und Polymethylmethaoryl andererseits liegt das Festigkeitsraaximura für ein Mischungsverhältnis 1 : 1 bei ca. 575 kp/cm und daiait etwa ca. 100 kp/ora über den Werten der beiden Komponenten. Bei der gemeinsamen thermoplastischen Verwaisung von nachebloriertem Polyvinylchlorid und Polymethacrylat entstehen transparente homogen aussehende Polymeren-Mischungen, deren maximale Festigkeit bei ca. 700 kp/cm liegt.For the transparent mixed film obtained on the same basis from a copolymer of vinyl chloride + vinyl acetate approx. 60; 40 on the one hand and polymethyl methaoryl on the other hand, there is a maximum of strength for a mixture ratio 1: 1 at approx. 575 kp / cm and daiait about approx. 100 kp / ora above the values of the two components. In the common thermoplastic orphanage of post-chlorinated Polyvinyl chloride and polymethacrylate result in transparent, homogeneous-looking polymer mixtures maximum strength is approx. 700 kp / cm.

Die Anwendung der gleichen Verarbeitungsweise oder der Extrusion für Gemische aus Polyvinylchlorid, Suspensionspolymerisat von K-Wert ca. 70 nach Fikentscher mit PoIymethylmethacrylat führt zu Polymer-wischungen mit maximaler Festigkeit bei einem Gew.-Verhältnis von ca. 60 : 40.The use of the same processing method or extrusion for mixtures of polyvinyl chloride, suspension polymer A K value of approx. 70 according to Fikentscher with polymethyl methacrylate leads to polymer wiping with a maximum Strength at a weight ratio of approx. 60:40.

Kombinationen von nachchloriertera Polyvinylchlorid mit Polyäthylacrylat in Äthylacetat-Lösungen bei einer Gesamtkonzentration von 10 % und in beliebigen Mischungsverhältnissen der Komponenten ergeben stabile iiischlösungen Und auch daraus homogen aussehende klare Filme. Die mechanischen Eigenschaften dieser Filme werden bezüglich ihrer Gesohmeidigkeit weitgehend vom Polyäthylacrylat be-Combinations of post-chlorinated polyvinyl chloride with polyethyl acrylate in ethyl acetate solutions at a total concentration of 10 % and in any mixing ratio of the components result in stable mixtures and also clear films that look homogeneous from them. The mechanical properties of these films are largely determined by the polyethyl acrylate in terms of their smoothness.
