  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.

  Described are polymeric foams made from polypropylene random copolymers that have a high melt strength and a high stiffness, and that provide beneficial mechanical properties for expanded bead foam (EPP) applications. The polypropylene random copolymers, at least in part, help to address existing challenges of accessing new EPP applications requiring higher stiffness, while maintaining a relatively low melting temperature, and a melt flow rate (MFR) of about 6 to about 10, that is usually used for EPP applications.
