Description

Verfahren zur Herstellung, von Kunststoffen Die Erfindung bezieht sich auf, die Herstellung von Kunststoffen aus. Polyacrylsäureverbindungen. Es wurde gefunden, .daß man Kunststoffe von besonders guten Eigenschaften dadurch erhält, :daß man Mischpolymerisaten aus Acrylsäure oder ihren funktionellen Derivaten, wie Acrylsäureestern, und aus Methacrylsäureestern Phthalsäureestex oder Acetine als Weichmachungsmittel einverleibt.Process for the production, of plastics The invention relates focus on the manufacture of plastics. Polyacrylic acid compounds. It was found that plastics with particularly good properties are obtained by : that one copolymers of acrylic acid or its functional derivatives, such as Acrylic acid esters, and from methacrylic acid esters Phthalic acid estex or Acetine as Incorporated plasticizers.

Die Weichmacher können den Mischpolymerisaten einverleibt oder auch bereits den zu polymerisierenden Verbindungen zugefügt und der Polymerisationsvorgang in Gegenwart der Weichmachungsmittel durchgeführt werden.The plasticizers can be incorporated into the copolymers or else already added to the compounds to be polymerized and the polymerization process be carried out in the presence of the plasticizers.

Durch die Einverleibung von Phthalsäureestern oder Acetin:en als Weicbmachungsmittel kann man Kunststoffe erzielen, welche sich durch besonders gute mechanische Eigenschaften auszeichnen.By incorporating phthalic acid esters or acetin: en as a plasticizer you can achieve plastics that have particularly good mechanical properties distinguish.

Es ist bereits vorgeschlagen worden, Polyvinylestern und Polystyrol Phthalsäureester als Weichmachungsmittel einzuverleiben. Hieraus konnte nicht geschlossen werden, daß man durch Einverleibung von Phthalsäure:estern oder Acetinen zu Mischpolymerisaten der vorstehend ;gekennzeichneten Art Erzeugnisse von besonders wertvollen Eigenschaften herstellen kann, z. B. solche, welche die bekannten in bezug auf Dehnung' und Schlagfestigkeit übertreffen. Den erfindtuzgsgemäß herzustellenden Erzeugnissen können gegebenenfalls auch noch andere organische Stoffe, wie z. B. Celluloseester oder Ph.enolformaldehydkondensationsprodukte, in untergeordneten Mengen einverleibt werden.It has been proposed to use polyvinyl esters and polystyrene Incorporating phthalic acid esters as plasticizers. This could not be deduced from this be that by incorporating phthalic acid: esters or acetins to form copolymers of the type identified above, products with particularly valuable properties can produce, e.g. B. those that are known in terms of elongation 'and impact resistance surpass. The products to be manufactured according to the invention can optionally also other organic substances, such as. B. cellulose esters or Ph.enolformaldehyde condensation products, be incorporated in subordinate quantities.

Beispiele i. Ein Polymerisat aus einer Mischung von 45 Teilen Methacrylsäureäthylester und 45 Teilen Acrylsäuremethylester wird mit io Teilen Monoacetin (Glycerinmonoacetat) in geeigneter Weise vermischt.Examples i. A polymer made from a mixture of 45 parts of ethyl methacrylate and 45 parts of acrylic acid methyl ester is mixed with 10 parts of monoacetin (glycerol monoacetate) appropriately mixed.

2. 52 Teile Methacrylsäuremethylester, 35 Teile Acrylsäureäthylester, io Teile Phthalsäureamylester, 3 Teile Phthralsäuremethylglykolester werden in Gegenwart eines Lösungsmittels in . der Wärme polymerisiert. Durch Verdunsten des Lösiungsmittels wird ein dehnbarer, klar durchsichtiger Film erhalten.2. 52 parts of methyl methacrylate, 35 parts of ethyl acrylate, 10 parts amyl phthalate and 3 parts methyl phthalate are in the presence of a solvent in. the heat polymerizes. By evaporation of the solvent a stretchable, clear, transparent film is obtained.
