Procedure for accelerating the ionic polymerization of lactams with more than six ring members, characterized in that the lactams, in the absence of water, using the usual alkaline catalysts, polymerize in the presence of catalytic amounts of compounds of the general formula **(See formula)** or O = C = N-R'-N = C = O or of substances that are capable of forming such compounds, where R1, R2 and R3 signify alkyl, cycloalkyl or aryl moieties, R4 and R5 signify the same moieties or a hydrogen atom and R'signifies an alkylene, cycloalkylene or arylene moiety.
