METHOD FOR MAKING POLYAMIDES |
摘要 |
The invention concerns a continuous method for making polyamides. The polyamides are of the type derived from diacids and diamines. The method comprises a process which consists in continuously mixing a compound rich in amine terminal groups and a compound rich in acid terminal groups and a step which consists in the polycondensation of said mixture. The invention also concerns the starting phase of said method, during which an aqueous solution is used comprising a mixture of monomers in substantially stoichiometric proportions.
