| Abstract: | Syndiospecific silyloxy‐functionalized polystyrene with high molecular weight was prepared using a (pentamethylcyclopentadienyl)titanatrane/MMAO catalyst system. The resulting polymer is soluble in polar organic solvents such as THF and shows good thermal stability. In addition, the compound Ni(acac)2 was used as a catalyst in preparing authentic atactic polymer of 4‐tert‐butyldimethylsilyloxystyrene under the same conditions. The chemical transformation of syndiospecific poly(4‐tert‐butyldimethylsilyloxystyrene) also gave a new polar polymer, namely syndiotactic poly(4‐hydroxystyrene) which is unattainable by traditional synthetic methods. |
