In their previous work15, the authors polymerized styrene with anionic catalysts containing the optically active alkyl group such as optically active amylsodium or triamylaluminum combined with titanium trichloride. The purpose was to obtain optically active polystyrene, in which one helical configuration (either right-or left-handed screw helix) presumably induced by the active group might be predominantly present. However, the attempt was not ...
