摘要： THE METHOD CONSISTS IN CARRYING OUT THE KNOWN ALKALINE POLYMERIZATION OF LACTAMS, HAVING AN AT LEAST SEVEN-MEMBERED RING, IN THE PRESENCE OF A COMPOUND OF THE GENERAL FORMULA

(R1-CO-C(-R2)(-R3)-CO-NH)N-X

WHEREIN X IS THE REST OF THE USED AMINE WITH N AMINO GROUPS, R1, R2 AND R3 ARE ALKYL, CYCLOALKYL, ARYL OR ARALKYL GROUPS WITH 1 TO 18 CARBON ATOMS, EITHER SEPARATED OR FORMING TOGETHER A RING, N IS AN INTEGER, AND EITHER R2 OR R3 CAN BE ALSO A HYDROGEN ATOM, IF N IS GREATER THAN 1. THE REST X CAN BE EITHER PLAIN OR SUBSTITUTED HYDROCARBON RADICAL SUCH AS ALKYLENE, ARYLENE, DIALKYL ETHER, DIALKYL THIOETHER, DIARYL THIOETHER, DIARYLSULFONE, DIALKYL AMINE, DIARYL AMINE, POLYVINYL- OR POLYSTYRYL REST DERIVED FROM THE CORRESPONDING AMINE WITH N AMINO GROUPS. ANY SUBSTITUENT ON THE REST X, WHICH DOES NOT INTERFERE WITH ACTIVATED ALKALINE POLYMERIZATION OF LACTAMS CAN BE USED, THAT IS ANY CHEMICALLY INERT, NON-ACIDIC SUBSTITUENT SUCH AS ALKYL, ALKOXYL AND THE LIKE.
