    • In the anionic polymerization of 2-methoxystyrene in toluene at 20 °C, side reactions were suggested to occur by Smets et al. (J. Polym. Sci. A-1, 1969, 7, 2859). However, we found that the polymerizations of this monomer in THF at -78 °C with secBuLi gave good molecular weight control with narrow molecular weight distributions (Afw/Mn < 1.05).

    • A. Hirao, unpublished results. 31 a and 31 b underwent anionic polymerization quantitatively in THF at -78 °C with cumylpotassium for 1 h. The A/n values of the resulting polymers of 31 a and 31 b were observed to be controlled in the range of 1000050000 g/mol. These polymers possessed narrow molecular weight distributions, A/w/A/n values being less than 1.05.
