DONOR SILANES
SiSiB Silane donors are used in combination with Ziegler-Natta catalysts to increase the isotactic index of Polypropylene.

Different silane donors with differing organoalkoxy structures are used depending on the exact nature of the catalyst and the type of polypropylene being manufactured. Organic substituents, such as cyclohexyl, cyclopentyl, methyl, isobutyl and phenyl, are some of the organic groups attached to silicon. The alkoxy groups are either methoxy or ethoxy with one, two, or three alkoxy groups on the silane molecule.
