Abstract: A PROCESS FOR THE ANIONIC POLYMERIZATION OF LACTAMS IS DISCLOSED, WHEREIN THE LACTAMS ARE POLYMERIZED IN THE PRESENCE OF A CATALYST AND A PROMOTER, WITH THE PROMOTER BEING DI-$-CAPROLACTIM-ETHER-DIHYDROCHLORIDE OR DI-$-CAPROLACTIM-EITHER-MONOHYDROCHLORIDE, WHICH LATTER COMPOUND MAY CONTAIN UP TO 90 MOLE PERCENT OF DI-$-CAPROLACTIM-EITHER. THE PROMOTERS OF THE PRESENT INVENTION ALLOW THE POLYMERIZATION TIME TO BE REDUCED. THE POLYMERIZATION OF LACTAMS PRODUCES USEFUL POLYAMIDES.
