haut degré "
La présente invention concerne la préparation de masses polymérisées à un haut degré, et de préférence la préparation de masses plastiques et déformables polymérisées à un haut degré, qui, comme groupements porteurs^, présentent des liaisons biurétiques entre les différents groupes organiques.
Selon l'invention, on obtient des produits de ce genre en faisant réagir des diurées organiques qui présentent des
<EMI ID=2.1>
ou avec d'autres composés qui réagissent comme eux, donc par exemple aussi moyennant emploi de composés qui, à côté d'un groupe isocyanate, contiennent encore un autre groupe réagissant comme le groupe isocyanate, par exemple un groupe chlo-rure carbamique etc. 448264
Il est déjà connu de former en partant de diisocyanates ou de leurs dérivés, tels que les diuréthanes, d'une part, et de diamines, d'autre part, des produits ou articles à poids moléculaire élevé, dont le groupe porteur est le groupe urée. De même, on sait déjà qu'en partant de diisocyanates et d'aminoalcools on peut fabriquer des masses et des articles façonnés ou profilés de ce genre. Enfin, il y a aussi lieu de se référer à cet égard aux amides qui, sous forme de polyamides ou de superpolyamides, constituent des composés particulièrement appropriés.
Les produits que l'on peut obtenir selon la présente invention présentent comme groupe porteur non plus ou non plus exclusivement un groupement urée ou uréthane, mais au moins un, et de préférence plus d'un, donc par exemple deux ponts de structure analogue à celle du biuret.
Pour la réalisation du procédé, on fait réagir des
<EMI ID=3.1>
urées, les co-amino-urées, d'une part, avec des composés bifonctionnels, d'autre part, dont les groupes réactifs identiques ou différents sont soit le groupe isocyanate, acide carbamique, ester carbamique, amide carbamique ou chlorure carbamique, mais surtout le groupement halogénylamide, très réactif. Il s'agit donc par exemple de composés des formules générales suivantes:
<EMI ID=4.1>
<EMI ID=5.1>
<EMI ID=6.1>
<EMI ID=7.1>
<EMI ID=8.1>
de, ester, anhydride ou uréthane ou être substituée d'une autr�
<EMI ID=9.1>
aliphatique, araliphatiques, hétérocyclique ou mixte, qui peut également être substitué et qui peut aussi être interrompu de
<EMI ID=10.1>
<EMI ID=11.1>
différents de l'espèce déjà indiquée, formant des urées avec les amines.
A cela s'ajoute encore les dichlorures de triazine, par
<EMI ID=12.1>
Au lieu des diurées et de préférence au lieu d'une partie de celles-ci, on peut employer les oxyurées et les aminourées du type spécifié plus haut; en particulier les oxyalcoylène-urées sont utilisables avec succès. A côté de cela, on peut aussi condenser en présence d'additions de diamines, de
<EMI ID=13.1>
première condensation ou une condensation complémentaire ou finale.
Parmi les composés du type indiqué, ceux qui ont un poids moléculaire élevé sont particulièrement utilisables; mais, en tout cas, il faut qu'au moins un des composants de condensation ait un poids moléculaire relativement élevé si l'on veut fabriquer des résines artificielles. De même, un
<EMI ID=14.1>
l'on veut produire des masses pouvant être mises sous forme de fils.
Parmi les composés convenant particulièrement à la réaction selon le procédé, on ne citera ici, parmi les innombra bles composés, que les suivants:
Tétra-, penta-, hexa-, octa-méthylène-diurée, oxy-tétra-méthy-
<EMI ID=15.1>
<EMI ID=16.1>
pentaméthylène-diisocyanique.
Pour préparer les produits de réaction, on chauffe de préférence à l'abri de l'oxygène de l'air, à l'état dissous ou,
<EMI ID=17.1>
soit suffisamment haute,, ou- jusqu'à ce que l'on puisse tirer de
<EMI ID=18.1>
tés.
La valeur des masses artificielles à groupements diurée
<EMI ID=19.1>
formément à l'invention, peut encore être notablement augmentée par un traitement subséquent à l'aldéhyde formique. Le traitement a lieu de préférence pour des valeurs du pH de 3 à 5. Les masses ainsi raffinées peuvent être employées comme laques, mais aussi comme masses artificielles à presser etc. Les masses artificielles sont propres à la.fabrication de pellicules, fils, fibres, rubans, feuilles, boyaux. Elles peuvent à cette fin être additionnées, de la manière habituelle, de diluants, de plastifiants et d'agents analogues.
Les exemples qui suivent sont destinés à mettre en lu-
<EMI ID=20.1>
tation à ce qui est décrit ici à titre d'exemple.
SCELLES.
<EMI ID=21.1>
diurée et 1 molécule-gramme de diisocyanate d'hexaméthylène dans une quantité double de dioxane et on les chauffe à l'abri de l'oxygène de l'air pendant plusieurs heures au réfrigérant à reflux. Après environ 2 heures on chasse le solvant par distillation et l'on élève lentement la température. On continue ensuite à condenser dans une atmosphère d'azote jusqu'à ce que la masse possède une viscosité suffisante pour l'usage envisagé.

high degree "
The present invention relates to the preparation of masses polymerized to a high degree, and preferably to the preparation of plastic and deformable masses polymerized to a high degree, which, as carrier groups ^, exhibit biuretic bonds between the various organic groups.
According to the invention, products of this type are obtained by reacting organic diureas which exhibit
<EMI ID = 2.1>
or with other compounds which react like them, therefore for example also by means of the use of compounds which, besides an isocyanate group, contain yet another reacting group such as the isocyanate group, for example a carbamic chloride group etc. 448264
It is already known to form, starting from diisocyanates or their derivatives, such as diurethanes, on the one hand, and diamines, on the other hand, products or articles with a high molecular weight, the carrier group of which is the group urea. Likewise, it is already known that, starting from diisocyanates and amino alcohols, it is possible to manufacture masses and shaped or shaped articles of this kind. Finally, reference should also be made in this regard to amides which, in the form of polyamides or superpolyamides, constitute particularly suitable compounds.
The products that can be obtained according to the present invention have as carrier group no longer or no longer exclusively a urea or urethane group, but at least one, and preferably more than one, therefore for example two bridges of structure similar to that of biuret.
For carrying out the process, reacting
<EMI ID = 3.1>
ureas, co-amino-ureas, on the one hand, with bifunctional compounds, on the other hand, the reactive groups of which are identical or different are either the isocyanate group, carbamic acid, carbamic ester, carbamic amide or carbamic chloride, but especially the halogenylamide group, very reactive. They are therefore, for example, compounds of the following general formulas:
<EMI ID = 4.1>
<EMI ID = 5.1>
<EMI ID = 6.1>
<EMI ID = 7.1>
<EMI ID = 8.1>
of, ester, anhydride or urethane or be substituted by another �
<EMI ID = 9.1>
aliphatic, araliphatic, heterocyclic or mixed, which can also be substituted and which can also be interrupted from
<EMI ID = 10.1>
<EMI ID = 11.1>
different from the species already indicated, forming ureas with the amines.
To this is also added triazine dichlorides, for
<EMI ID = 12.1>
Instead of diureas and preferably instead of a part thereof, oxyureas and aminoureas of the type specified above may be employed; in particular oxyalkylene ureas can be used successfully. Besides this, it is also possible to condense in the presence of additions of diamines, of
<EMI ID = 13.1>
first condensation or a complementary or final condensation.
Among the compounds of the type indicated, those which have a high molecular weight are particularly useful; but, in any event, at least one of the condensation components must have a relatively high molecular weight if artificial resins are to be made. Likewise, a
<EMI ID = 14.1>
we want to produce masses that can be put in the form of threads.
Among the compounds which are particularly suitable for the reaction according to the process, only the following will be mentioned here, among the innumerable compounds:
Tetra-, penta-, hexa-, octa-methylene-diurea, oxy-tetra-methyl-
<EMI ID = 15.1>
<EMI ID = 16.1>
pentamethylene diisocyanic.
To prepare the reaction products, heating is preferably carried out in the absence of oxygen in the air, in the dissolved state or
<EMI ID = 17.1>
is high enough ,, or- until one can derive from
<EMI ID = 18.1>
your.
The value of artificial masses with diurea groups
<EMI ID = 19.1>
formally according to the invention, can still be significantly increased by a subsequent treatment with formaldehyde. The treatment is preferably carried out for pH values of 3 to 5. The thus refined masses can be used as lacquers, but also as artificial pressing masses etc. Artificial masses are suitable for the manufacture of films, threads, fibers, tapes, sheets, guts. For this purpose, they may be added, in the usual manner, with diluents, plasticizers and similar agents.
The examples which follow are intended to illustrate
<EMI ID = 20.1>
tion to what is described here by way of example.
SEALS.
<EMI ID = 21.1>
diurea and 1 gram molecule of hexamethylene diisocyanate in double the amount of dioxane and heated in the absence of oxygen in the air for several hours in a reflux condenser. After about 2 hours the solvent is removed by distillation and the temperature is slowly raised. Condensation is then continued in a nitrogen atmosphere until the mass has sufficient viscosity for the intended use.
