  • PROCESS FOR PRODUCING A CONCENTRATED AQUEOUS SOLUTION OF A SALT OF A DIAMINE AND DICARBOXYLIC ACID
    Publication number: 20230071006
    Abstract: The present invention relates to a process for producing a highly concentrated aqueous solution of a salt of a diamine and dicarboxylic acid by using a pre-salt aqueous solution having a high concentration of diacid/diamine salt and an excess of dicarboxylic acid; and adding additional diamine to obtain the final diacid/diamine solution. The final diacid/diamine salt solution obtained is suitable for the manufacture of a polyamide such as for example polyamide 66.

  • Process for producing aromatic polyimides
    Patent number: 10647814
    Abstract: The invention relates to a process for producing an aromatic polyimide, comprising the following steps: (a) preparing one or more salt(s) by reacting one or more aromatic tetracarboxylic acid(s) in the solid state and one or more diamine(s), optionally in the presence of one or more chain limiter(s), in the presence of one or more binder(s), comprising one or more organic liquid(s), in an amount of from 1% to 25% by weight relative to the total weight of the aromatic tetracarboxylic acid(s), of the diamine(s) and of the optional chain limiter(s), then; (b) polymerising the salt(s) obtained in step (a).
