摘要： A spherical carrier for olefin polymerization catalysts has at least one magnesium-containing compound having a structure represented by formula (1). The spherical carrier has a relatively good particle morphology, and substantially no abnormally morphological particles will appear. A method for preparing the spherical carrier can be used to prepare a carrier having a small particle size and greatly expands the particle size range of the preparable carrier. When the catalyst prepared by using the carrier is used for olefin polymerization, polymerization activity is good, substantially no abnormally morphological material is present, and hydrogen response is good.

摘要： Disclosed is a polypropylene with an MFR of at least 20 g/10 min comprising a homopolypropylene and optionally within a range from 2 wt % to 30 wt % of an propylene-α-olefin copolymer by weight of the polypropylene; wherein the homopolypropylene has a MFR within a range from 30 g/10 min to 200 g/10 min, an Mw/Mn within a range from 7 to 16, and comprising 1.1 wt % or less atactic polypropylene based on the total weight of the homopolypropylene and atactic polypropylene, where the propylene-α-olefin copolymer has within a range from 30 wt % to 50 wt % α-olefin derived units by weight of the propylene-α-olefin copolymer, and an intrinsic viscosity within a range from 4 to 8 dL/g. The impact copolymer may be obtained by combining a Ziegler-Natta catalyst having at least two different internal electron donors with propylene in reactors in series to produce the homopolypropylene followed by a gas phase reactor to produce a propylene-α-olefin copolymer.
