Alkylalkoxysilanes are important catalysts in Ziegler-Natta polymerisation.

Depending on the exact nature and the type of catalyst, different silane donors with various organoalkoxy structures are used.

Silane donors Advantages:

  • Increase the yield of polymer per unit weight of catalyst.
  • Increase the isotactic content of polypropylene-based polymers
  • Improvement of the molecular weight dispersity of the polymer
