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
