New metallocene support catalyst for syndiotactic styrene type polymer polymerization

摘要

(57) Abstract This invention offers the catalyst which for polymerizing the syndiotactic styrene type polymer is supported. The description above the catalyst which is supported (A) the polymer, (B) the backing and (C) consists of transition metal chemical compound, (D) (a) reacts with transition metal chemical compound selectively and the chemical compound which can form the ion mixture or (b) oxygen - content chemical compound, and (E) it is possible furthermore to include the alkyl aluminum compound outside that. The catalyst where this invention is supported with the co-catalyst produces the styrene type polymer which possesses high activity and high syndiotactic arrangement characteristic. The desirable aforementioned co-catalyst is arukiruaruminokisan.
