Product Description
Abbreviation: DCPDMS
Product Name: Donor-D
CAS number: 126990-35-0
Structural formula:
Boiling point ℃: 251
Note: This product can greatly improve the crystallinity, isotacticity and apparent density of polyolefin products. The polypropylene produced has the characteristics of high crystallinity and low melt flow rate, which is a strong electron donor. It can be used alone or in combination with other electron donors to suit the production of different grades of polypropylene.
