    摘要: The present invention generally relates to a catalyst system. The catalyst system can include a metal dioxide of titanium dioxide or hafnium dioxide, as well as a cocatalys of the general formula (IV) or (V): M′(s+)(O-isopropyl)s  (IV) R3SiX  (V) where: M′ is Al, Ca, Na, K, Si or Mg, s is an integer from 1 to 4 and is the oxidation state of the metal, R is alkyl having 1 to 10 C atoms or aryl having 6 to 20 C atoms, and X is F, Cl, Br, CN; or the general formulae (CH3)2Clsi(CH2)2SiCl(CH3)2 (CH3)2ClSi(CH2)3CN [(CH3)3Si]2O [(CH3)3Si]2NH or [(CH3)3Si]2.
