摘要:
A process for preparing syndiotactic vinylidene aromatic polymers comprising contacting one or more vinylidene aromatic monomers with a hydrocarbylsilane or di(hydrocarbyl)silane adjuvant to form a monomer/silane mixture and contacting the monomer/silane mixture with a catalyst composition comprising a Group 4 metal complex and an activating cocatalyst.
