【Abstract】 The polymerization mechanism and commercial research for the syndiotactic polymerization of polypropylene were reviewed. Meanwhile, the supporting methods of metallocene catalysts and the polymerization process were introduced. Confronting with problems such as low bulk density of sPP and reactor fouling, it has been emphasized that the studies of reaction engineering focused on developing an optimal process for catalyst support and special polymerization process are very important.更多还原
