  Provided in the present invention is a solid catalyst component for use in olefin polymerisation, comprising Mg, Ti, a halogen, and at least one electron donor, the electron donor being a 2-substituted amino-phenyl ester compound selected from general formula (I). Also disclosed in the present invention are a catalyst comprising the solid catalyst component, and an application for the catalyst in olefin polymerisation, particularly in propylene polymerization. Also provided in the present invention is a high activity catalyst, said catalyst being able to obtain polypropylene of high isotacticity and wide molecular weight distribution, and not requiring an external electron donor to obtain high isotacticity polypropylene; during polymerization, Al/Ti and Al/Si are reduced, the polymerization time is lengthened, and high activity can still be maintained, suitable for producing low-ash polymers.

  本发明提供了一种用于烯烃聚合的固体催化剂组分，包括 Mg、Ti、卤素和至少一种电子供体，电子供体为选自通式 (I) 的 2-取代氨基苯基酯化合物。本发明还公开了一种包含固体催化剂组分的催化剂，以及该催化剂在烯烃聚合，特别是丙烯聚合中的应用。本发明还提供了一种高活性催化剂，所述催化剂能够获得高同素异形度和宽分子量分布的聚丙烯，并且不需要外部电子供体即可获得高同素异形度聚丙烯；在聚合过程中，Al/Ti 和 Al/Si 降低，聚合时间延长，仍可保持高活性，适用于生产低灰分聚合物。
