Polymerization of monomers containing functional silyl groups. 12. Anionic polymerization of styrene derivatives para‐substituted with pentamethyldisilyl (Si‐Si), heptamethyltrisilyl (Si‐Si‐Si), and nonamethyltetrasilyl (Si‐Si‐Si‐Si) groups

Macromolecular Symposia, 1995
AbstractThree styrene derivatives, para‐substituted pentamethyldisilyl (Si‐Si), heptamethyltrisilyl (Si‐Si‐Si), and nonamethyltetrasilyl (Si‐Si‐Si‐Si) groups 1 ‐ 3 were synthesized and polymerized in tetrahydrofuran (THF) at −78°C and in benzene at 40°C.
