Description

Verfahren zur Herstellung linearer und vernetzter polymerer Verbindungen aus Triphosphornitrilderivaten Es sind bereits zahlreiche Versuche unternommen worden, hochpolymere Verbindungen aus anderen als Kohlenstoff im Gerüst enthaltenden Verbindungen herzustellen. Bekannt sind beispielsweise die unter dem Namen Silikone geläufigen polykondensierten Alkyl- oder Arylsiliciumoxy de. Es hat nicht an Versuchen gefehlt, auch andere Polymere, beispielsweise mit Phosphor- und Stickstoffbindungen - wie im Phosphornitrilchlorid - aufzubauen. Die bisher hier erhaltenen Verbindungen sind aber nur niedermolekular und cyclisch, wie beispielsweise Triinere oder Tetramere. Soweit sie hochpolymer und kettenförmig sind, werden sie sehr leicht hydrolysiert.Process for the production of linear and crosslinked polymeric compounds from triphosphoronitrile derivatives Numerous attempts have already been made high polymer compounds made from compounds other than carbon in the skeleton to manufacture. For example, those known under the name of silicones are known polycondensed alkyl or aryl silicon oxides. There has been no lack of attempts also other polymers, for example with phosphorus and nitrogen bonds - such as in phosphorus nitrile chloride - build up. The compounds obtained so far here are but only of low molecular weight and cyclic, such as, for example, triners or tetramers. To the extent that they are highly polymeric and chain-like, they are very easily hydrolyzed.

Es wurde nun gefunden, daß hochpolymere, absolut feuchtigkeitsbeständige Verbindungen, die gleichzeitig einen sehr hohen Erweichungspunkt aufweisen und gegenüber längerer Hitzeeinwirkung äußerst beständig sind, erhalten werden, wenn man bestimmte trimere Derivate des Phosphorni,trilchlorids durch eine Verknüpfung der Ringe zu Hochpolymeren verbindet. Solche zur Umsetzung geeigneten Derivate des triineren Phosphornitrils sind beispielsweise Verbindungen der Formel: R3 P3 N3 X3, worin R gleiche oder verschiedene Alkyl- oder Arylreste bedeutet und X Halogenatom oder Hydroxylgruppen. Falls X3 1 Chloratom und zwei Hydroxylgruppen darstellt, ist es möglich, durch Reaktion mit Phosgen zu einer Ringverknüpfung zu gelangen, wobei im wesentlichen eine lineare Struktur erreicht wird. Die allgemeine Formel für hochpolymere Verbindungen, die durch Umsetzung der obengenannten Triphosphornitrilderivate entstanden sind, ist: Abgesehen davon, daß man aus den bereits erwähnten trimeren und tetranieren Phosphornitrilchloriden durch Umsetzung mit sekundären aromatischen Aminen wieder nur trimere und tetrainere Kondensationsprod,ukte erhält, müssen diese bei der Aufarbeitung zum Teil erst fein vermahlen werden, um die Verunreinigungen mit geeigneten Lösungsmitteln entfernen zu können. Die Umsetzung selbst erfordert höhere Temperaturen entsprechend dem zweiten Reaktionspartner. Es ist auch bekannt, Phosphornitrilverbindungen mit Alkoholen, Mercaptanen, aliphatischen Aminen, Alkylchloriden und anderen chlorierten Verbindungen zu Polymeren umzusetzen. Jedoch erfolgt diese Umsetzung in zwei Stufen. In der ersten Stufe wird ein verhältnismäßig niedermolekulares Kondensationsprodukt gebildet, und zwar bei höheren Temperaturen. Erst in der zweiten Stufe wird dieses Kondensationsprodukt bei Temperaturen zwischen 200 bis 400° C zu einem harzartigen Produkt polymerisiert.It has now been found that highly polymeric, absolutely moisture-resistant compounds, which at the same time have a very high softening point and are extremely resistant to prolonged exposure to heat, are obtained if certain trimeric derivatives of phosphorus trilchloride are combined by linking the rings to form high polymers. Such derivatives of triiner phosphorus nitrile which are suitable for conversion are, for example, compounds of the formula: R3 P3 N3 X3, in which R denotes identical or different alkyl or aryl radicals and X denotes a halogen atom or hydroxyl groups. If X3 represents 1 chlorine atom and two hydroxyl groups, it is possible to achieve a ring linkage by reaction with phosgene, a substantially linear structure being achieved. The general formula for high-polymer compounds that have arisen from the reaction of the above-mentioned triphosphoronitrile derivatives is: Apart from the fact that only trimeric and tetranated condensation products are obtained from the trimeric and tetranated phosphonitrile chlorides already mentioned by reaction with secondary aromatic amines, some of these must first be finely ground during work-up in order to be able to remove the impurities with suitable solvents . The reaction itself requires higher temperatures corresponding to the second reactant. It is also known to react phosphonitrile compounds with alcohols, mercaptans, aliphatic amines, alkyl chlorides and other chlorinated compounds to form polymers. However, this implementation takes place in two stages. In the first stage, a relatively low molecular weight condensation product is formed, specifically at higher temperatures. Only in the second stage is this condensation product polymerized to a resinous product at temperatures between 200 and 400 ° C.

Hingegen erhält man erfindungsgemäß bei der Umsetzung der eingangs der Beschreibung angeführten trimeren Derivate des Phosphornitrilchlorids mit Phosgen bereits in der ersten Stufe durch mäßiges Erwärmen kettenförmige Polymere von hohem Molekulargewicht und mit einem Schmelzpunkt - je nach Kettenlänge - von 300 bis 350° C. Die Aufarbeitung ist sehr einfach, da kein unverbrauchtes Ausgangsmaterial zurückbleibt und lediglich zur restlosen Entfernung des Lösungsmittels eine geringfügige Zerkleinerung zweckmäßig ist. Die so erhaltenen Polymeren sind in aliphatischen und aromatischen Kohlenwasserstoffen unlöslich, in chlorierten aromatischen Kohlenwasserstoffen beim Erhitzen löslich. Sie sind reversibel thermoplastisch und weisen gute elastische Eigenschaften auf. Durch Formpressen bzw. Auswalzen lassen sich Formstücke und Folien herstellen. Beispiel In eine Mischung aus 2000 g Hexan und 30 g Pyridin werden 435 g (1 Mol) Triphenyl-dihydroxyphosphornitrilchlorid eingetragen. Nach Erwärmen auf 40 bis 50° C wird sodann Phosgen - vorerst in langsamem Strom - eingeleitet. Nach etwa 10 Minuten scheidet sich zunächst ein öliges Produkt ab, welches sich unter stetigem Einleiten von Phosgen schnell verfestigt. Nach etwa zweistündiger Reaktionsdauer unter Rückfluß und Feuchtigkeitsabschluß ist die Reaktion durchgeführt. Nach der Trennung vom Lösungsmittel und Zerkleinerung wird das angefallene Harz durch Erwärmen auf 90 bis 100° C vollkommen vom Lösungsmittel befreit.In contrast, according to the invention, the implementation of the initially obtained trimeric derivatives of phosphonitrile chloride with phosgene listed in the description chain-like polymers of high already in the first stage by moderate heating Molecular weight and with a melting point - depending on the chain length - from 300 to 350 ° C. Working up is very simple, as there is no unused starting material remains and only a slight one for the complete removal of the solvent Comminution is appropriate. The polymers thus obtained are aliphatic and aromatic hydrocarbons, insoluble in chlorinated aromatic hydrocarbons soluble on heating. They are reversible thermoplastic and have good elasticity Properties on. Moldings and foils can be produced by compression molding or rolling produce. Example In a mixture of 2000 g of hexane and 30 g 435 g (1 mol) of triphenyldihydroxyphosphoronitrile chloride are added to pyridine. After heating to 40 to 50 ° C, phosgene is then - initially in a slow stream - initiated. After about 10 minutes, an oily product separates out, which solidifies rapidly with the constant introduction of phosgene. After about The reaction is two hours under reflux and with exclusion of moisture carried out. After separation from the solvent and comminution, the resulting Resin completely freed from solvent by heating to 90 to 100 ° C.
