Die Verbindungen der Formel I werden erfindungsgemäss zum flammhemmenden Ausrüsten von Methylmethacrylatpo-lymeren und Copolymeren verwendet. Überraschenderweise zeigen Verbindungen der Formel I gemäss der obigen Definition, worin R3 eine von Wasserstoff verschiedene Bedeutung hat oder R] oder R2a und R2b eine von Aethyl verschiedene Bedeutung haben, eine bessere Löslichkeit in monomerem Methylmethacrylat und können darum schon vor der Polymerisation derselben eingesetzt werden. Die Verbindung 8 der Tabelle und ähnliche Verbindungen mit schlechterer Löslichkeit in Methylmethacrylat können jedoch (gemäss Beispiel 6) in einer geeigneten Apparatur (z. B. in einem Extruder) ohne weiteres bei Schmelztemperatur in Polymethylmethacrylat eingearbeitet werden und entfalten dann die gleiche Wirkung wie die übrigen Verbindungen. According to the invention, the compounds of the formula I are used for the flame-retardant finishing of methyl methacrylate polymers and copolymers. Surprisingly, compounds of the formula I according to the above definition, in which R3 has a meaning different from hydrogen or R] or R2a and R2b have a meaning other than ethyl, show better solubility in monomeric methyl methacrylate and can therefore be used even before the polymerization thereof. However, compound 8 in the table and similar compounds with poorer solubility in methyl methacrylate (according to example 6) can be easily incorporated into polymethyl methacrylate at a melting temperature in a suitable apparatus (e.g. in an extruder) and then develop the same effect as the others Links.
Die Methylmethacrylatpolymere werden in an sich bekannter Weise durch Polymerisation von Methylmethacrylat mit gegebenenfalls weiteren Comonomeren erhalten. Für die Herstellung von Copolymerisaten kommen als Comono-mere a, ß-einfach ungesättigte Verbindungen, z.B. Alkyl-(C2_ 8)ester der Methacrylsäure oder Alkyl-(Ci_8)ester der Acryl-säure, Alkyl-(Ci_8)ester der a-Cyanacrylsäure wie die entsprechenden Äthyl-, Butyl- oder Cyclohexylester, im weiteren auch Styrol, Methylstyrol, Acrylnitril, Methacrylnitril, a-Chloracrylnitril und verwandte Verbindungen in Frage, vorzugsweise Alkyl-(C2-8)-methacrylate oder Alkyl-(Ci_8)-acry-late. The methyl methacrylate polymers are obtained in a manner known per se by polymerizing methyl methacrylate with optionally further comonomers. Comonomers for the preparation of copolymers are a, β-monounsaturated compounds, e.g. Alkyl (C2_8) esters of methacrylic acid or alkyl (Ci_8) esters of acrylic acid, alkyl (Ci_8) esters of a-cyanoacrylic acid such as the corresponding ethyl, butyl or cyclohexyl ester, and also styrene, methylstyrene, acrylonitrile , Methacrylonitrile, a-chloroacrylonitrile and related compounds in question, preferably alkyl (C2-8) methacrylates or alkyl (Ci_8) acrylic latex.
Eine bevorzugte Form eines Copolymerisates wird erhalten, wenn die Polymerisation des Methylmethacrylates in Gegenwart von Glycidylacrylat und/oder Glycidylmethacry-lat, vorzugsweise Glycidylmethacrylat, durchgeführt wird. Vorzugsweise enthalten die Methylmethacrylatpolymeren A preferred form of a copolymer is obtained when the polymerization of the methyl methacrylate is carried out in the presence of glycidyl acrylate and / or glycidyl methacrylate, preferably glycidyl methacrylate. The methyl methacrylate polymers preferably contain
0,1-10 Gew.% und bevorzugt 0,5-6 Gew.% der Glycidylver-bindung, bezogen auf die Summe von Methylmethacrylat, io und gegebenenfalls weitere Comonomere. 0.1-10% by weight and preferably 0.5-6% by weight of the glycidyl compound, based on the sum of methyl methacrylate, 10% and optionally further comonomers.
Zur Einarbeitung der flammhemmenden Mittel in die Methylmethacrylatpolymeren können die verschiedenen bekannten Verfahren angewendet werden. Verbindungen der (II), Formel I oder deren Gemische können den Monomeren bzw. i5 den Präpolymeren beigemischt werden, wobei sich die Verbindungen bei einer Temperatur von 20-60 ° C lösen sollen. Darauf werden die erfindungsgemässen flammgehemmten Polymere in an sich bekannter Weise, vorzugsweise mittels Blockpolymerisation in Gegenwart von Polymerisationskata-20 lysatoren, z. B. Azo- bis -isobutyronitril, Dibenzoylperoxid, Dilaurylperoxid oder Tertiärbutoxyperpivalat, hergestellt. Die flammhemmenden Mittel können auch in das geschmolzene Polymere eingearbeitet werden, worauf man das geschmolzene Material nach an sich bekannten Methoden, 25 z. B. Spritzguss oder Extrusion, in geformte Teile überführt. Bevorzugt verwendet man 3-30 Gew.%, vorzugsweise 8-25 Gew.% der Verbindungen der Formel I oder deren Gemische Hai (III), bezogen auf die eingesetzten Monomeren bzw. auf das einge setzte Polymer. The various known methods can be used to incorporate the flame retardants into the methyl methacrylate polymers. Compounds of (II), formula I or mixtures thereof can be added to the monomers or i5 to the prepolymers, the compounds being said to dissolve at a temperature of 20-60 ° C. The flame-retardant polymers according to the invention are then analyzed in a manner known per se, preferably by means of block polymerization in the presence of polymerization catalysts, e.g. B. azo bis isobutyronitrile, dibenzoyl peroxide, dilauryl peroxide or tertiary butoxyperpivalate. The flame retardants can also be incorporated into the molten polymer, whereupon the molten material can be prepared by methods known per se, e.g. B. injection molding or extrusion, converted into molded parts. It is preferred to use 3-30% by weight, preferably 8-25% by weight, of the compounds of the formula I or their mixtures of shark (III), based on the monomers used or on the polymer used.
30 Die Herstellung erfindungsgemäss flammgehemmter Copolymeren des Methylmethacrylats und gegebenenfalls weiterer Comonomerer mit Glycidylacrylat und/oder Glycidylmethacrylat erfolgt ausschliesslich mittels Blockpolymerisation. In diesem Falle verwendet man bevorzugt 3-25 35 Gew.%, vorzugsweise 8-15 Gew.% der Verbindungen der Formel I oder deren Gemische bezogen auf die eingesetzten Monomeren. 30 The flame-retardant copolymers of methyl methacrylate and, if appropriate, further comonomers with glycidyl acrylate and / or glycidyl methacrylate are produced exclusively by means of block polymerization. In this case, 3-25 35% by weight, preferably 8-15% by weight, of the compounds of the formula I or their mixtures, based on the monomers used, are preferably used.
Weitere Additive können zugegeben werden, z.B. Polymerisationsregler, Weichmacher, UV-Stabilisatoren, Antioxyd-40 antien, Pigmente usw. Die flammgehemmten Methylmethacrylatpolymeren können in an sich bekannter Weise weiter zu Formkörpern, z.B. Platten, Rohren oder Folien verarbeitet werden. Other additives can be added, e.g. Polymerization regulators, plasticizers, UV stabilizers, antioxidants, antigens, pigments, etc. The flame-retardant methyl methacrylate polymers can be further formed into shaped articles, e.g. Sheets, pipes or foils can be processed.
In den folgenden Beispielen bedeuten die Teile Gewichts-45 teile; die Prozente Gewichtsprozente. Die Temperaturen sind in Celsiusgraden angegeben. In the following examples the parts mean 45 parts by weight; the percentages by weight. The temperatures are given in degrees Celsius.
Beispiel 1 example 1
In einem Rührgefäss werden 23,6 Teile 2-Äthyl-2-methyl-5o 1,3-propandiol bei 50° geschmolzen. Es werden 30,7 Teile Phosphoroxytrichlorid zugetropft und die Mischung 15 Stunden bei Raumtemperatur gerührt. Anschliesend wird im Vakuum 1 Stunde auf 50° erwärmt. Zum erhaltenen Kristallbrei werden bei Raumtemperatur 21 Teile Pyridin und 1,8 55 Teile Wasser gegeben und die Mischung 1 Stunde bei Raumtemperatur, anschliessend 4 Stunden bei 40° gerührt. Nach beendeter Reaktion kühlt man auf Raumtemperatur und filtriert vom Niederschlag ab. Nach dem Einengen der organischen Phase wird der Rückstand in Toluol aufgenommen, 6o mehrmals mit verdünnter wässriger Salzsäure gewaschen und über Natriumsulfat getrocknet. Danach wird das organische Lösungsmittel abdestilliert. 23.6 parts of 2-ethyl-2-methyl-5o-1,3-propanediol are melted at 50 ° in a stirred vessel. 30.7 parts of phosphorus oxytrichloride are added dropwise and the mixture is stirred at room temperature for 15 hours. The mixture is then heated to 50 ° in a vacuum for 1 hour. 21 parts of pyridine and 1.8 55 parts of water are added to the crystal slurry obtained at room temperature and the mixture is stirred at room temperature for 1 hour and then at 40 ° for 4 hours. When the reaction is complete, the mixture is cooled to room temperature and the precipitate is filtered off. After concentrating the organic phase, the residue is taken up in toluene, washed several times with dilute aqueous hydrochloric acid and dried over sodium sulfate. The organic solvent is then distilled off.
