The catalytic activity of various alkyl chlorides in the polymerization of N-phenylethylenimine was studied from the structural point of view. Both the polymerization rate and the molecular weight of the polymer obtained varied with the kind of alkyl chloride. The rate of monomer consumption is expressed by a first-order rate equation with respect to the monomer concentration in the early stage of the polymerization. The efficiency factors of the catalysts differ with the kind of alkyl chloride and increase with an increase in the reaction time. When the chloride of a conjugated alkyl group is used, the polymerization rate decreases with an increase in the ionization potential of the alkyl radical, while it increases when chlorides of a non-conjugated alkyl are used. The structural study of the catalytic activity of the alkyl chloride was made quantitatively from the energetic point of view.
