Abstract:
The present invention relates to a method for increasing the recyclability of a polyamide in a sintering process, wherein at least 4000 ppm of at least one acid is incorporated in the polyamide, said acid being selected from: the acids of general formula HxPyOz in which x, y and z are integers selected in the range from 1 to 7, boric acid, the salts of these acids, their esters, their anhydrides and mixtures thereof.
