| titleOfInvention | Improved method for producing transparent polyamides |
| abstract | The present invention generally relates to a process for the manufacture of transparent polyamides comprising the step of polycondensing a monomer mixture comprising at least one dicarboxylic acid and at least one cycloaliphatic diamine, wherein the cycloaliphatic diamine comprises a Two rings connected by an alkylene group of 6 carbon atoms, each ring being replaced by an amine group and at least one alkyl group containing 1-6 carbon atoms, which may be the same or different, the method being characterized in that, The diamine was decomposed into six isomer fractions when it was subjected to analysis by gas chromatography on a non-polar column, and the isomer fractions were named isomers according to their elution order. When the body fractions I to VI are used, the mass content F I of the fraction I of the alicyclic diamine does not exceed 35%. The invention also relates to the use of such cycloaliphatic diamines for the production of transparent polyamides. Finally, the present invention relates to transparent polyamides and formulations obtainable using said method, as well as articles obtained from such polyamides or from such formulations. |
