The present invention relates to a process for preparing an active monomer composition comprising at least one lactam and / or lactone, one catalyst, and one active agent, and because the composition is stable to polymerization, the storage of the resulting monomer composition is prevented. It is about how to make it possible. The monomer composition is used, inter alia, in the production of polyamide moldings via ring opening, anionic polymerization. |
