Anionic living polymerizations of monomers with functional silyl groups are reviewed. The monomers include styrenes and 1, 3-butadiene derivatives containing Si-OR, Si-NEt2, Si-H, Si-O-SiMe3, Si-SiMe3, Si-CH2-CH =CH2, and Si-CH =CH2. The polymerizations of these monomers with anionic initiators such as butyllithium, alkali-metal naphthalenides and oligo (α-methylstyryl) dialkali-metal salts, always proceed without chain transfer and termination reactions to afford stable living polymers, although the limited conditions are required in some cases. The polymers with controllable molecular weights and narrow molecular weight distributions (Mw/Mn≤ 1.1) are obtained in all cases described here. Synthesis of new types of block copolymers with styrene. isoprene with these monomers are also discussed.
