Diisobutyldimethoxysilane (IBIPDMS ,Donor-I ) CAS:111439-76-0

Used in propylene polymerization as external electron donor for producing special polypropyleneresin grades.

Diisobutyldimethoxysilane is a chemical compound with the formula (CH3O)2Si(CH2)4CH(CH3)2. It is an organosilicon compound, and it consists of a silicon atom bonded to two methoxy (-OCH3) groups and two isobutyl (-CH2CH(CH3)2) groups. 

Diisobutyldimethoxysilane is a colorless liquid with a faint sweet odor. It is commonly used as a coupling agent or crosslinker in polymer chemistry, where it can improve the adhesion between different materials or increase the strength and rigidity of polymers through crosslinking reactions.
