Solid catalyst component for propylene polymerization and catalyst |
| abstract |
The present invention provides catalyst for polymerization of a propylene prepared from by using a solid catalyst component for polymerization of a propylene which is prepared by subjecting a dialkoxymagnesium (a), a tatravalent halogen-containing titanium compound (b), and a diester of maleic acid (c) each having a straight-chain or branched chain alkyl group having a carbon number of 2 to 8 into contact with one another by suspending the foregoing components in an aromatic hydrocarbon which melting point is 50 to 150° C. (d), an organic aluminum compound represented by the general formula:R<1>pAlQ3-p, and an organic silicon compound represented by the general formula R<2>qSi(OR<3>)4-q. By using the catalyst for a polymerization of a propylene, an excellent hydrogen response can be shown and a polymer having a high stereoregularity can be obtained in a high yield. |
