Abstract:
A method for making polyamide is described. More particularly, a method for making a polyamide from at least one diacid and one diamine, that includes a step of concentrating an aqueous solution of diacid and diamine salt up to a salt weight concentration higher than 85%, and a polymerization step up to a desired polymerization degree is described.
