Whether in the automotive, packaging, toys or cosmetics industry – polypropylene is omnipresent and virtually indispensable to many modern industrial applications. Donor silanes from WACKER make an invaluable contribution to the chemical genesis of this plastic.

The production of polypropylene by olefin polymerisation is of enormous technical and economic importance. It is essential here to control the stereospecificity. That ensures a high proportion of isotactic polymer, which is essential for producing high-quality products that have good physical and polymer properties.

Donor silanes serve as co-catalysts in the Ziegler-Natta polymerization of polypropylene. They guarantee a high content of isotactic polymer, control the molecular weight and are thus crucial to the quality of the end polymer.
