## Abstract The polymerization of acrylonitrile initiated by methoxo‐β‐diketone nickel chelates of the [Ni(L)(CH~3~O)(CH~3~OH)]~n~ type and pyridine was studied. Chelating agents L employed included acetylacetone, ethylacetoacetate, and salicylaldehyde. These systems could initiate the polymerizati
