Abstract: POLY-B-AMIDES ARE PREPARED IN A TWO-PAHSE DISPERSION BY POLYMERIZING B-LACTAMS WHICH ARE UNSUBSTITUTED AT THE NITROGEN ATOM. ONE OF THE PAHSES CONSISTS OF AN ALIPHATIC OR A CYCLOALIPHATIC HYDROCARBON AND THE OTHER OF A SOLUTION OF THE LACTAM IN A HIGHLY POLAR SOLVENT. THE PREPARATION IS CARRIED OUT IN THE PRESENCE OF CATALYSTS, PROMOTERS AND EMULSIFIERS, THE POLY-B-AMIDES PRODUCED ARE SUITABLE FOR THE MANUFACTURE OF MOLDED ARTICLES, FILMS AND FILAMENTS.
