Beschreibung
Zusammenfassung:	The invention relates to a supported main catalyst of propone polymerization. The relative donor compound is represented as following, wherein the donor arranges a new succinate compound with large substituent group and helical structure on molecular skeleton, therefore, the inventive main catalyst has high catalytic activity to catalyze propone polymerization, the product polypropylene has high stereoregularity, and while assisted with promoter, the catalyst can obtain polypropylene with different regularities. The invention further discloses a preparation method of the main catalyst.
