Abstract: The invention relates to a continuous method for preparing polyamide by condensation, the method comprising the following consecutive steps: a) melting a mixture comprising polyamide monomers in an extruder or co-kneader, the monomers being delivered to the extruder or co-kneader without any water being added; and b) carrying out the polycondensation reaction of the mixture obtained at the end of step a) in a horizontal mixer-reactor, steps a) and b) of the method being carried out at a pressure close to atmospheric pressure.

Abstract: A process for manufacturing a transparent polyamide including a step of polycondensation of a mixture of monomers including at least one dicarboxylic acid and at least one cycloaliphatic diamine, in which the cycloaliphatic diamine includes two rings linked by an alkylene group including 1 to 6 carbon atoms, each ring being substituted by an amine group and at least one alkyl group, which may be identical or different, including 1 to 6 carbon atoms, wherein the diamine decomposes into six isomer fractions when it is subjected to analysis by gas chromatography on a nonpolar column and, when the isomer fractions are named isomer fractions I to VI in their order of elution, the mass content FI of fraction I of the cycloaliphatic diamine does not exceed 35%. A transparent polyamide capable of being obtained by the process, and to articles obtained from such a polyamide or from such a formulation.
