Zusammenfassung:PURPOSE:To prepare the titled compound useful as a polymerization catalyst, in high quality and yield, by reacting 2,2'-hydrazo-bis(4-methoxy-2,4-dimethylvalero- nitrile) with a halogen at a specific low temperature, and separating the objective compound at a specific temperature. CONSTITUTION:2,2'-Hydrazo-bis(4-methoxy-2,4-dimethylvaleronitrile) of formulaI is made to react with the halogen of formula X2 (e.g. Cl, Br, etc.) at -60- -11 deg.C, and the crystals precipitated from the reaction liquid are separated at
