Aus der JP-B-73/0 00 877 ist die Herstellung von Polyformaldehyd durch Polymerisieren von cyclischen Formaldehydoligomeren, wie Trioxan oder Tetraoxymethylen, unter Verwendung von Phosphorpentoxid in halogenierten oder nitrierten Kohlenwasserstoffen bekannt. Phosphorpentoxid wird in Mengen von 0,0001 bis 1 Gew.-%, bezogen auf das zu polymerisierende Formaldehydoligomere eingesetzt. Als inertes Verdünnungsmittel werden beispielsweise Di- und Trichlorethan, Nitroethan, Nitromethan oder Nitrobenzol in Mengen von 0,3 bis 20 Teilen pro Teil Formaldehydoligomer eingesetzt.From JP-B-73/0 00 877 is the production of polyformaldehyde Polymerization of cyclic formaldehyde oligomers, such as trioxane or Tetraoxymethylene, using phosphorus pentoxide in halogenated or nitrated hydrocarbons known. Phosphorus pentoxide is in Amounts from 0.0001 to 1 wt .-%, based on the formaldehyde oligomer to be polymerized used. As an inert diluent, for example Di- and trichloroethane, nitroethane, nitromethane or nitrobenzene in amounts of 0.3 to 20 parts per part of formaldehyde oligomer used.

Aus der EP-B 00 01 004 sind polymere Acetalcarboxylate bekannt, die durch Polymerisieren von Glyoxylsäureestern in Gegenwart von Initiatoren erhältlich sind. Diese Polymerisate enthalten als charakteristisches Merkmal mindestens 4 Einheiten der FormelFrom EP-B 00 01 004 polymeric acetal carboxylates are known which pass through Polymerization of glyoxylic acid esters in the presence of initiators are available. These polymers contain as a characteristic Characteristic at least 4 units of the formula

wobei M für Alkalimetall, Ammonium, C₁- bis C₄-Alkyl und Alkanolamingruppen steht. Die Herstellung der Polymeren ist jedoch aufwendig, weil man die Monomeren, d. h. die Formylester, zunächst durch Erhitzen der Halbacetalester von Glyoxylsäure in Gegenwart von Phosphorpentoxid herstellen und reinigen muß. Die gereinigten Aldehydester werden dann mit geeigneten Initiatoren polymerisiert, beispielsweise mit Bortrifluorid, Phosphorpentafluorid, Zinnchlorid, Aminen, Hydroxyl- und Cyanidionen oder mit Diethylnatriummalonat. Die so erhältlichen Polyglyoxylsäureester werden mit Alkalimetallbasen oder Ammoniak verseift. Man erhält dabei die entsprechenden Salze von Polyglyoxylsäuren. Diese Salze werden als biologisch abbaubare Zusätze für Waschmittel verwendet.where M is alkali metal, ammonium, C₁ to C₄ alkyl and alkanolamine groups stands. However, the preparation of the polymers is complex because the monomers, d. H. the formyl esters, first by heating the Semi-acetal ester of glyoxylic acid in the presence of phosphorus pentoxide  must manufacture and clean. The cleaned aldehyde esters are then with suitable initiators polymerized, for example with boron trifluoride, Phosphorus pentafluoride, tin chloride, amines, hydroxyl and cyanide ions or with diethyl sodium malonate. The polyglyoxylic acid esters obtainable in this way are saponified with alkali metal bases or ammonia. You get the corresponding salts of polyglyoxylic acids. These salts are considered organic degradable additives used for detergents.

Die US-PS 42 33 423 betrifft die Stabilisierung eines Polyacetalcarboxylats in Gegenwart eines Säurekatalysators mit genügender Menge eines Acetals, das 3 bis 20 C-Atome besitzt. Der entstehende Alkohol wird durch den Zusatz von Molekularsieben oder von Phosphorpentoxid gebunden.The US-PS 42 33 423 relates to the stabilization of a polyacetal carboxylate in the presence of an acid catalyst with a sufficient amount of one Acetals, which has 3 to 20 carbon atoms. The alcohol produced is through the addition of molecular sieves or of phosphorus pentoxide.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Polyglyoxylaten durch Polymerisieren von Glyoxylsäureestern in Gegenwart von Initiatoren zur Verfügung zu stellen, bei dem direkt stabile Polyglyoxylate anfallen.The present invention has for its object a method for Production of polyglyoxylates by polymerizing glyoxylic acid esters in the presence of initiators, at which directly stable polyglyoxylates are obtained.

Die Aufgabe wird bei dem eingangs beschriebenen Verfahren dadurch gelöst, daß man als Polymerisationsinitiator Phosphorpentoxid einsetzt. Das Phosphorpentoxid wird in Mengen von 0,001 bis 15 Gew.-%, bezogen auf die Glyoxylate der Formel II angewendet. Die Polymerisation kann in Gegenwart oder auch in Abwesenheit von inerten Lösemitteln durchgeführt werden. Sofern man in einem inerten Lösemittel polymerisiert, betragen die Monomerkonzentrationen 1 bis 99%, vorzugsweise 5 bis 95 Gew.-%. Als inerte Lösemittel eignen sich Ether, Nitrile und/oder Chlorkohlenwasserstoffe. Besonders bevorzugt werden Dichlormethan, Tetrahydrofuran oder Acetonitril. Beim Polymerisieren in Dichlormethan liegen die Monomerkonzentrationen vorzugsweise bei 70 bis 90 Gew.-%, während sie in Tetrahydrofuran vorzugsweise 5 bis 50 Gew.-% betragen.The object is achieved in the method described at the outset by that phosphorus pentoxide is used as the polymerization initiator. The phosphorus pentoxide is in amounts of 0.001 to 15 wt .-%, based on the Glyoxylates of formula II applied. The polymerization can take place in the presence or can also be carried out in the absence of inert solvents. If you polymerize in an inert solvent, the monomer concentrations are 1 to 99%, preferably 5 to 95% by weight. As inert Solvents are suitable for ether, nitrile and / or chlorinated hydrocarbons. Dichloromethane, tetrahydrofuran or acetonitrile are particularly preferred. When polymerizing in dichloromethane, the monomer concentrations are preferably at 70 to 90% by weight while in tetrahydrofuran preferably 5 to 50% by weight.

Nach dem erfindungsgemäßen Verfahren werden Glyoxylate der FormelAccording to the method of the invention, glyoxylates of the formula

polymerisiert, in der M=C₁- bis C₄-Alkyl bedeutet. Vorzugsweise verwendet man als Monomer Glyoxylsäuremethylester und Glyoxylsäureethylester. Die bevorzugt in Betracht kommenden Initiatormengen an Phosphorpentoxid betragen 0,1 bis 10 Gew.-%, bezogen auf die Monomeren der Formel II. polymerized in which M = C₁ to C₄ alkyl. Preferably is used as the monomer glyoxylic acid methyl ester and glyoxylic acid ethyl ester. The preferred initiator amounts of phosphorus pentoxide amount to 0.1 to 10 wt .-%, based on the monomers of Formula II.  

Die Monomeren der Formel II können gegebenenfalls mit anderen Aldehyd-Gruppen tragenden Verbindungen copolymerisiert werden, z. B. mit Verbindungen der FormelThe monomers of formula II can optionally with other aldehyde groups bearing compounds are copolymerized, e.g. B. with connections of the formula

Die Verbindungen der Formel III können mit den Verbindungen der Formel II in jedem beliebigen Verhältnis miteinander copolymerisiert werden. Weitere Comonomere für die Verbindungen der Formel II sind: C₁-C₄-Aldehyde, C₂-C₄-Alkylenoxide, Epihalogenhydride und Epoxibernsteinsäure.The compounds of formula III can with the compounds of formula II be copolymerized with each other in any ratio. Further Comonomers for the compounds of the formula II are: C₁-C₄ aldehydes, C₂-C₄ alkylene oxides, epihalohydrides and epoxy succinic acid.

Die nach dem erfindungsgemäßen Verfahren erhältlichen Polymerisate werden in Form der Alkali-, Ammonium- oder Alkanolamin-Salze als Builder in Waschmitteln verwendet. Überraschenderweise erhält man bei der Verwendung von Phosphorpentoxid als Katalysator stabile Polymere. Dies war aufgrund der Lehre der US-A-42 33 423 nicht zu erwarten, weil nach den dort gemachten Angaben Phosphorpentoxid als Agenz nur nach Abschluß der Polymerisation bei der Stabilisierung der Polymeren eingesetzt wird.The polymers obtainable by the process according to the invention are in the form of the alkali, ammonium or alkanolamine salts as a builder in Detergents used. Surprisingly, you get when using of phosphorus pentoxide as a catalyst stable polymer. This was due the teaching of US-A-42 33 423 is not to be expected, because according to those made there Information on phosphorus pentoxide as an agent only after completion of the polymerization is used in the stabilization of the polymers.
