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.

Fourth, characteristics and uses
This product is a new type of external electron donor for olefin polymerization. Due to its unique and excellent performance in olefin polymerization, it greatly improves the crystallinity, isotacticity and apparent density of polyolefin products. The resulting polypropylene has the characteristics of high crystallinity and low melt flow rate, and belongs to a strong electron donor. It can be used alone or in combination with other electron donors to adapt to the production of different grades of polypropylene; when used with a variety of catalysts, it can make the performance and efficiency of the catalyst fully play.
