Description
Proeédé pour la préparation d'un nouveau polymère synthétique. Le brevet principal porte sur un procédé pour la préparation d'une nouvelle résine synthétique, par polycondensation, à chaud, de l'acide N-éthanolamino-1.1-iindécandïque.
Le présent brevet concerne un procédé de préparation d'une nouvelle résine d'un type analogue, moulable à chaud.
Ce procédé est caractérisé en ce qu'un mé lange d'acide N-éthanolamino-11-undécanoïque et d'acide ll.-amino-undécanoïque est chauffe. l'état fondu jusqu'à gélification.
Le copolycondensat obtenu est insoluble dans les solvants du poly-undécanamide: form- amide, acétamide, acide acétique, acide mono- chloracétique.
Son point de ramollissement et sa dureté varient selon la teneur du mélange initial en acide N-éthanolamino-11-undécanoïque.
La gélification dudit mélange se produit d'autant plus rapidement que la teneur du mélange initial en acide N-éthanolamino-1.1- undécanoïque est plus élevée. Le chauffage (déshydratation) est effectué de préférence sous vide poussé, du moins pour les faibles teneurs en acide N-éthanolamino-1.1-undéca- noïque.
Pour des teneurs de 1 à 51/o, le mélange réactionnel passe d'abord par un état thermo plastique, filable, avec un point de fusion légèrement plus élevé que celui du poly-undé- eanamide (point de fusion:
195 C par exem- ple, pour un pourcentage de 2%). Après géli- fieation, la résine thermodurcissable ne fond plus, mais se ramollit et devient translucide à 250 C.
Pour un pourcentage en acide N-éthanol- amino-11-undécanoïque compris entre 5 et 50 %, le mélange réactionnel passe encore par un état thermoplastique, mais il devient très difficilement filable à partir d'un pourcen tage de 10 0/0.
La résine obtenue après gélification de vient extrêmement dure et résistante au choc. Elle se ramollit, en devenant translucide, entre 300 et 320 C.
Pour des teneurs plus élevées que 50 11/o en acide N-éthanolamino-11-undécanoïque, la gélification se produit très rapidement. Le co- polycondensat devient plus élastique. Il se ra mollit vers 300 C.
Process for the preparation of a new synthetic polymer. The main patent relates to a process for the preparation of a novel synthetic resin, by hot polycondensation of N-ethanolamino-1.1-indecandic acid.
The present patent relates to a process for preparing a novel resin of a similar type, hot moldable.
This process is characterized in that a mixture of N-ethanolamino-11-undecanoic acid and 11-amino-undecanoic acid is heated. the molten state until gelation.
The copolycondensate obtained is insoluble in the solvents of the poly-undecanamide: form-amide, acetamide, acetic acid, mono-chloroacetic acid.
Its softening point and its hardness vary according to the content of the initial mixture of N-ethanolamino-11-undecanoic acid.
The gelation of said mixture occurs all the more rapidly as the content of the initial mixture of N-ethanolamino-1.1-undecanoic acid is higher. The heating (dehydration) is preferably carried out under high vacuum, at least for the low contents of N-ethanolamino-1.1-undecanoic acid.
For contents of 1 to 51 / o, the reaction mixture first passes through a thermoplastic, spinnable state, with a melting point slightly higher than that of poly-undeeanamide (melting point:
195 C for example, for a percentage of 2%). After gelation, the thermosetting resin no longer melts, but softens and becomes translucent at 250 C.
For a percentage of N-ethanol-amino-11-undecanoic acid of between 5 and 50%, the reaction mixture still passes through a thermoplastic state, but it becomes very difficult to spin from a percentage of 10%.
The resin obtained after gelation becomes extremely hard and impact resistant. It softens, becoming translucent, between 300 and 320 C.
For contents higher than 50 11 / o of N-ethanolamino-11-undecanoic acid, gelation occurs very quickly. The co-polycondensate becomes more elastic. It softens around 300 C.
