Abstract

A process for the preparation of polyamides by polymerization of dodecanolactam, the dodecanolactam being heated in the presence of at least one acid catalyst while excluding oxygen, wherein said process is characterized in that an aqueous solution is used as the acid catalyst. of phosphoric acid, and that the mixture of dodecanolactam, water and phosphoric acid is maintained at a temperature of at least 250º C until a macromolecular product with reactive end groups is formed from the dodecanolactam, after which the water is extracted. the mixture by evaporation, and the macromolecular product containing the phosphoric acid is made to continue to polymerize in an inert atmosphere, maintaining it at a temperature of at least 260º C.
