It has been shown that initiation of the anionic polymerization of ethylene oxide by 9-methylfluorenyl alkali salts is a simple process of addition whereas side reactions occur for fluorenyl salts. Reactivities of different kinds of ionic species were determined by spectropbotometry in the case of 9

Al~tract--The behaviour of 9-methylfluorenyl alkali salts is nearly the same as that of the corresponding fluorenyl salts, as shown by studies of the effects of temperature, counterion and solvent on the ultraviolet and visible spectra. A marked shift in ). max on substituting a methyl group on the
