Diphenyldimethoxysilane（DDS） CAS：6843-66-9

This product is an additive for high-efficiency carrier catalysts for propylene polymerization, and plays a role in improving isotacticity.

Diphenyldimethoxysilane is an organosilicon compound with the chemical formula (C6H5)2Si(OCH3)2.  It is a colorless to light yellow liquid that is soluble in organic solvents such as benzene, ether, and chloroform.

Diphenyldimethoxysilane is widely used as a coupling agent and adhesion promoter in many industrial applications, including coatings, adhesives, sealants, and rubber.  It reacts with hydroxyl groups on the surface of substrates such as glass, ceramics, metals, and plastics to form stable covalent bonds, improving the adhesion between the substrate and the applied coating or adhesive.

In addition, diphenyldimethoxysilane can also be used as a crosslinking agent in the synthesis of polymers.  It can react with polymer chains containing hydroxyl or amino groups to form crosslinked networks, which improve the mechanical properties and thermal stability of the resulting polymers.

Diphenyldimethoxysilane should be handled with care as it may be toxic if ingested or inhaled, and may cause skin and eye irritation upon contact.  Proper safety precautions should be taken when handling this compound.
