ABSTRACT:
An improved process for the preparation of a lactam-magnesium compound which involves bringing into intimate admixture a lactam monomer represented by the following structural formula: ##STR1## wherein Y is an alkylene group having from 3 to 12 carbon atoms, in particulate form, and an organomagnesium-containing material. The process is carried out at a temperature below the melting point of the lactam monomer but at a temperature sufficient to convert at least a portion of the lactam monomer to said lactam-magnesium compound in pulverulent form. The lactam-magnesium compound is useful as a catalyst for anionic lactam polymerization.
