Diisopropyldimethoxysilane (DIPDMS, Donor-P) CAS:18230-61-0

Used as catalyst in propylene polymerization as external electron donor. High activity, high stereoselectivity, strong melt fluidity during polymerization.

Diisopropyldimethoxysilane (DIPDMS) is a chemical compound with the molecular formula C8H20O2Si. It is an organosilicon compound that belongs to the group of alkoxysilanes. DIPDMS is a clear, colorless liquid that has a faint sweet odor. It is soluble in organic solvents such as alcohols and ethers, but insoluble in water.

DIPDMS is used in various applications, including as a cross-linking agent for silicone rubber, as a coupling agent for fiber glass-reinforced plastics, and as a surface modifier for metal and glass surfaces. It is also used as a precursor for the synthesis of other organosilicon compounds.

DIPDMS is flammable and may be harmful if ingested or inhaled. It should be handled with caution and stored in a cool, dry place away from heat sources and incompatible materials.
