Product Description

Abbreviation: DIBDMS
Product Name: Donor-B
CAS number: 17980-32-4
Structural formula:


Boiling point ℃: 118 ℃ / 80mm / Hg
Remarks: It has very good tunability for PP isotacticity and molecular weight. The outstanding feature is that the sensitivity of hydrogen modulation is quite good. Therefore, the effect of controlling the molecular weight and distribution of PP through hydrogen decoupling is significant.
