Abstract
L'invention concerne principalement un procédé de fabrication d'un polyamide transparent comprenant une étape de polycondensation d'un mélange de monomères comprenant au moins un diacide carboxylique et au moins une diamine cycloaliphatique, dans lequel la diamine cycloaliphatique comporte deux cycles reliés par un groupe alkylène comportant 1 à 6 atomes de carbone, chaque cycle étant substitué par un groupe amine et au moins un groupe alkyle pouvant être identique ou différent, comportant 1 à 6 atomes de carbone, caractérisé en ce que la diamine se décompose en six fractions d'isomères lorsqu'elle est soumise à une analyse par chromatographie gazeuse sur une colonne non polaire et que, lorsque lesdites fractions d'isomères sont nommées fractions d'isomères I à VI dans leur ordre d'élution, la teneur massique Fi en fraction I de ladite diamine cycloaliphatique n'excède pas 35%. Elle concerne par ailleurs aussi l'utilisation d'une telle diamine cycloaliphatique pour la fabrication d'un polyamide transparent. Elle concerne enfin un polyamide transparent ainsi qu'une formulation, susceptibles d'être obtenus par ledit procédé et des articles obtenus à partir d'un tel polyamide ou d'une telle formulation.
