Abstract

Process for the alkaline polymerization of lactams whose cycle comprises at least five carbon atoms, characterized in that the polymerization is carried out at a relatively low temperature, comprised between the melting point of the lactam and the melting point of the corresponding polyamide, presence at the same time of alkaline catalysts and of a cocatalyst, constituted by a polyoxyalkylene glycol dicarbamate of the formula: ** (See formula) ** where R = is aromatic, cyclic or divalent aliphatic radical, R 'means an atom of H or a radical CH3 n is an integer equal to or greater than 2, and p is an integer equal to or greater than 3.
