    摘要: Disclosed is a solid catalyst component for olefin polymerization. The catalyst component comprises a dialkoxy magnesium carrier, a titanium compound, and a product from an internal electron donor reacting in an inert solvent. Said internal electron donor compound comprises a 2,3-di-non-linear-alkyl-2-cyano succinic acid diester compound as presented in formula I: as in formula I, R1 and R2 radicals are independently chosen from linear or branched C1-C4 alkyl groups; R is chosen from C3-C6 iso-alkyl, sec-alkyl, or cycloalkyl groups. Also disclosed is another solid catalyst component. The catalyst component comprises a dialkoxy magnesium carrier, a titanium compound, and a product from an internal electron donor reacting in an inert solvent. In addition to a 2,3-di-non-linear-alkyl-2-cyano succinic acid diester compound as presented in formula I, the internal electron donor compound can also comprise 2-isopropyl-2-(3-methylbutyl)-1,3-dimethoxy propane and/or a carboxylic ester compound. Also disclosed is a catalyst containing the solid catalyst component. The catalyst is used for olefin polymerization, particularly propylene polymerization, and is relatively active during polymerization. The obtained polymer has the advantages of wide molecular weight distribution, high molecular bulk density, good hydrogen regulation sensitivity, good stereospecificity, good particle shape, and small fine powder content.

    摘要: A catalyst component (A) for olefin polymerization is prepared by contacting a solid component (a) containing magnesium, titanium, halogen and an internal electron donor compound with an organosilicon compound (b), wherein the organosilicon compound (b) is one or more selected from a Si—H functional group containing chainlike polysiloxane (b1) represented by formula (Ix), a cyclic polysiloxane (b2) represented by formula (Iy) and a Si—H functional group containing organosilicon compound (b3) represented by formula (Iz). In addition, a process for preparing the catalyst component and the corresponding catalyst is described. The catalyst component and its catalyst have high catalytic activity, good hydrogen response, and good stereospecificity, the catalyst can release its activity more evenly, and the obtained polymer has significantly increased bulk density. The definitions of R1 to R10, n and z in the formulae (Ix), (ly) and (Iz) are as described in the specification.
