Description

Gegenstand des deutschen Patentes 1 061 065 ist ein Verfahren zur Beschleunigung der peroxydisch bewirkten Härtung von Mischungen aus ungesättigten, Reste von phosphorhaltigen Säuren aufweisenden Polyestern mit daran anpolymerisierbären monomeren Vinylverbindüngen, wonach als Beschleuniger 0,001 bis 10% einer Verbindung der allgemeinen FormelThe subject of the German patent 1,061,065 is a process for accelerating the peroxidically effected Curing of mixtures of unsaturated polyesters containing residues of phosphoric acids with monomeric vinyl compounds that can be polymerized onto it, after which 0.001 to 10% of a compound of the general formula as an accelerator

R(N = C = O)2;R (N = C = O) 2 ;

verwendet wird, wobei χ eine ganze Zahl von 1 bis 4 und R einen gegebenenfalls noch durch andere mit Isocyanaten nicht reagierende Gruppen substituierten ein- oder mehrwertigen Alkyl-, Alkylen-, Aryl-, Aralkyl-, Alkylaryl-, Cycloalkyl- oder heterocyclischen Rest bedeutet. is used, where χ is an integer from 1 to 4 and R is a mono- or polyvalent alkyl, alkylene, aryl, aralkyl, alkylaryl, cycloalkyl or heterocyclic radical which is optionally substituted by other groups which do not react with isocyanates .

Es wurde nun gefunden, daß auch die peroxydisch bewirkte Härtung von Mischungen aus handelsüblichen phosphorfreien ungesättigten Polyesterharzen und monomeren phosphorhaltigen Vinyl- und Allylverbindungen, z. B. Triallylphosphit, Trimethallylphosphit oder Trimethallylphosphat, durch Zugabe von 0,001 bis 10% einer Verbindung der allgemeinen FormelIt has now been found that the peroxide-induced curing of mixtures of commercially available phosphorus-free unsaturated polyester resins and monomeric phosphorus-containing vinyl and allyl compounds, z. B. triallyl phosphite, trimethallyl phosphite or trimethallyl phosphate, by adding from 0.001 to 10% of a compound of the general formula

R . (N = C = O)x R. (N = C = O) x

wesentlich beschleunigt werden kann.can be accelerated significantly.

In der allgemeinen Formel bedeutet χ eine ganze Zahl von 1 bis 4 und R einen gegebenenfalls noch durch andere mit Isocyanaten nicht reagierende Gruppen substituierten ein- oder mehrwertigen Alkyl-, Alkylen-, Aryl-, Aralkyl-, Alkylaryl-, Cycloalkyl- oder heterocyclischen Rest.In the general formula, χ denotes an integer from 1 to 4 and R denotes a mono- or polyvalent alkyl, alkylene, aryl, aralkyl, alkylaryl, cycloalkyl or heterocyclic radical which is optionally substituted by other groups which do not react with isocyanates .

Die handelsüblichen ungesättigten Polyesterharzmassen sind Mischungen aus ungesättigten Polyestern, wie sie beispielsweise durch Kondensation von a,/?-ungesättigten mehrbasischen Carbonsäuren, vorzugsweise ungesättigten Dicarbonsäuren, wie Maleinsäure, Fumarsäure oder Itaconsäure, wobei ein Teil der ungesättigten Säuren durch gesättigte Säuren, z. B. Adipinsäure oder Phthalsäure, ersetzt sein kann, mit mehrwertigen Alkoholen, vorzugsweise Glykolen, wie Äthylenglykol und Diäthylenglykol, erhalten sind, und daran anpolymerisierbären Vinylverbindungen, z. B. Styrol.The commercially available unsaturated polyester resin compositions are mixtures of unsaturated polyesters like them for example by condensation of a, /? - unsaturated polybasic carboxylic acids, preferably unsaturated dicarboxylic acids, such as maleic acid, fumaric acid or Itaconic acid, some of the unsaturated acids being replaced by saturated acids, e.g. B. adipic acid or phthalic acid, can be replaced with polyhydric alcohols, preferably glycols, such as ethylene glycol and diethylene glycol, are obtained and thereon anpolymerisierbären vinyl compounds, e.g. B. styrene.

Das erfindungsgemäße Verfahren zur Härtung von Massen, die neben handelsüblichen Polyesterharzen im allgemeinen 0,1 bis 30% einer phosphorhaltigen monomeren Vinylverbindung enthalten, ist technisch deswegen von erheblicher Bedeutung, weil bei diesen Massen die sonst zur Beschleunigung der Härtung von Polyesterharzen eingesetzten üblichen Beschleunigungsmittel, z.B. Kobaltnaphthenat und Dimethalanilin, im allgemeinen versagen.The process according to the invention for curing masses which, in addition to commercially available polyester resins, im generally contain 0.1 to 30% of a phosphorus-containing monomeric vinyl compound, is therefore technical of considerable importance because with these masses the otherwise accelerated hardening of polyester resins common accelerating agents used, e.g., cobalt naphthenate and dimethalaniline, in general fail.

Selbstverständlich lassen sich auch Mischungen aus ungesättigten Polyestern und daran anpolymerisierbären phosphorhaltigen monomeren Vinyl- und Allylverbindungen erfindungsgemäß härten.Mixtures of unsaturated polyesters and polymerizable onto them can of course also be used Cure phosphorus-containing monomeric vinyl and allyl compounds according to the invention.

Als Beschleuniger seien beispielsweise genannt: Monoisocyanate, wie Octadecylisocyanat, n-Dodecylisocyanat,Examples of accelerators that may be mentioned are: monoisocyanates, such as octadecyl isocyanate, n-dodecyl isocyanate,

Zusammen mit Peroxyd-Katalysatoren, wie z. B. Dialkyl-, Diaryl-, Arylalkyl-, Acylperoxyden, vorzugsweise Hydroperoxyden, Persäuren und Perestern, bewirken die Substanzen der von der angeführten Formel umfaßten Verbindungsklasse eine schnellere und auch vorteilhaftere Härtung der Polyesterharze. So werden von den nach diesem Verfahren ausgehärteten Polyesterharzen bessere mechanische Werte und bessere Werte für die Wasseraufnahme erreicht, als wenn die genannten Peroxyde allein eingesetzt werden.Together with peroxide catalysts, such as. B. dialkyl, diaryl, arylalkyl, acyl peroxides, preferably Hydroperoxides, peracids and peresters cause the substances of the formula given included a class of compounds a faster and also more advantageous curing of the polyester resins. Be like that better mechanical values and better values of the polyester resins cured by this process for water absorption than when the peroxides mentioned are used alone.
