ABSTRACT:
Polymerization of epoxides and mixtures of epoxides with lactones and vinyl compounds, polymerizable through the action of cationic catalysts, is controlled by providing, in association with a radiation-sensitive catalyst precursor, a gelation inhibitor in the form of a cyclic amide in which the amide nitrogen atom contains unsubstituted hydrogen.
