Description
<Desc/Clms Page number 1>
Procédé pour la fabrication de polymères supérieurs en éther- -sel de l'acide carbamique d'aminoaloools.
On a trouvé que l'on peut obtenir des produits de poly- condensation de valeur, lorsqu'on traite par échauffement des combinaisons ayant la constitution
R''
N . R . 000 . NHR'
R'''
Les résidus R, R' etc. mentionnés dans la formule ci-des- sus signifient R une chaîne méthylénique avec au moins 4 ato- mes 0, qui ne peut pas comporter des substituants trop impor- tants,, par exemple des radicaux octadécyles diphényles ou
EMI1.1
naphthyles,'et qui peut être interrompue par des hétéroato- mes ou des résidus hydroaromatiques;.R' et R" peuvent être de l'hydrogène, un résidu alkyle ou aryle, R''' peut être de l'hydrogène ou un résidu acyle.
Un peut cependant aussi uti- liser les sels de ces combinaisons avec des acides qui sont volatiles à la température de condensation, par exemple de l'acide carbonique, de l'acide oxalique, de l'acide formique, de l'acide acétique, de l'acide valérique, de l'acide benzoï- que. Pour faciliter la compréhension, on cite ci-dessous quelques combinaisons

heptane-diol, pendant 4 heures, à 245 , dans un récipient sous pression.
Après ce temps on relâche la pression, on con- tinue pendant une heure à chauffer à la même température et on réduit la pression jusqu'à un vide de 3 mm. La réaction s'é- tant encore poursuivie pendant 4 heures, on obtient un produit ayant de très bonnes propriétés plastiques. On travaille à l'acide carbonique pour éliminer l'oxygène de l'air pendant la réaction de condensation.
La condensation s'opère de préférence sans que l'on fasse usage de diluants. On peut cependant aussi utiliser aes di- luants, comme par exemple du crésol, du phénol, de l'hydroxyle- diphényle, des hydrocarbures supérieurs, de l'huile de paraf- fine et ainsi de suite.
La condensation se fera aussi bien sous pression qu'à la pression atmosphérique. Dans certains cas un traitement sous vide permet de réduire le temps de réaction ou d'améliorer les propriétés. Dans ae nombreux cas, cependant, une combinaison des procédés, sous les conditions de pression les plus diverses est particulièrement avantageuse. Les températures de réaction se trouvent entre 1800 et 320 .
Le cas échéant on peut également ajouter des catalyseurs, notamment ue faibles quantités ae sels alcalins à réaction acide de métaux polyvalents, des stabilisateurs de viscosité des constitutions les plus diverses.
Selon le degré de polymérisation désiré, et selon les conditions de réaction, le temps de réaction est différemment long. Lorsque les conditions pour la fabrication d'un produit défini ont été déterminées empiriquement, on peut les repro- duire facilement. De même, l'addition de stabilisateurs de viscosité, dont le but est d'obtenir un point terminal bien défini, peut toujours être déterminée avec précision. Si l'on désire fabriquer des produits de teinte non modifiée, il est particulièrement avantageux d'exclure l'oxygène de l'air.
Les produits fabriqués d'après le présent procédé peuvent être mis en oeuvre seuls ou en combinaison avec d'autres pro- duits de polycondensation, de résines naturelles ou synthéti- ques, de dérivés cellulosiques, de matériaux de remplissage, de pigments, de matières colorantes, en vue de la production des objets façonnés les plus divers tels que films, feuilles, masses à presser.

A process for the manufacture of higher carbamic acid ether-salt polymers from aminoaloools.
It has been found that valuable polycondensation products can be obtained when heat-treating combinations having the constitution

The residues R, R 'etc. mentioned in the above formula mean R a methylenic chain with at least 4 O atoms, which cannot contain too large substituents, for example octadecyl diphenyl radicals or

heptanediol, for 4 hours, at 245, in a pressurized container.
After this time the pressure is released, the heating is continued for one hour at the same temperature and the pressure is reduced to a vacuum of 3 mm. As the reaction continued for a further 4 hours, a product having very good plastic properties was obtained. We work with carbonic acid to remove oxygen from the air during the condensation reaction.
The condensation takes place preferably without the use of diluents. However, thinners can also be used, such as, for example, cresol, phenol, hydroxyl diphenyl, higher hydrocarbons, paraffin oil and so on.
The condensation will take place under pressure as well as at atmospheric pressure. In certain cases a vacuum treatment makes it possible to reduce the reaction time or to improve the properties. In many cases, however, a combination of the processes under the most diverse pressure conditions is particularly advantageous. Reaction temperatures are between 1800 and 320.
If necessary, it is also possible to add catalysts, in particular small amounts of alkali metal salts with an acid reaction of polyvalent metals, and viscosity stabilizers of the most diverse constitutions.
Depending on the desired degree of polymerization, and depending on the reaction conditions, the reaction time is differently long. When the conditions for the manufacture of a defined product have been determined empirically, they can be easily reproduced. Likewise, the addition of viscosity stabilizers, the purpose of which is to obtain a well-defined end point, can always be determined with precision. If it is desired to produce products of unmodified shade, it is particularly advantageous to exclude oxygen from the air.
The products produced according to the present process can be used alone or in combination with other polycondensation products, natural or synthetic resins, cellulose derivatives, fillers, pigments, materials. dyestuffs, for the production of the most diverse shaped objects such as films, sheets, pressing masses.
