Ethene/norbornene copolymerization by [MeSi(3-(tert)BuCp) (N(tert)Bu)]TiCl2/MAO-catalyst.
Ethene/norbornene copolymerization by the catalyst system [Me2Si(3-(tert)BuCp) (N(tertBu)]TiCl2/ MAO was investigated in detail at 30 degrees C, 60 degrees C, and 90 degrees C. A mass flow controller was used in this work to obtain kinetic data and investigate temperature's effects on activity, norbornene incorporation, copolymerization parameter, microstructure, glass transition temperature, and molar masses were described. High copolymerization values r(E) and high alternation are determined. The number of isotactic alternating sequences is much higher than that of the syndiotactic alternating sequences.
