| titleOfInvention | Olefin polymerization catalyst and method for producing polypropylene using the same |
| abstract | (57) [Problem] A catalyst having high stereospecificity tends to increase the molecular weight of a polymer, and the required amount of hydrogen tends to increase when producing a high-molecular-weight polyolefin. This causes an increase in hydrogen consumption and an increase in polymerization pressure, In some cases, it is necessary to increase the pressure resistance of the polymerization reactor. [A] A solid titanium catalyst component containing Mg, Ti, a halogen and an electron donor, [B] an organometallic compound catalyst component, and [C] two or more atoms existing through a plurality of atoms. Compound contact product obtained by contacting a having a number more ether bonds and [I], [II] the general formula R 1 2 Si (OR 2) 2 (In the formula, R 1 represents a cyclic amino group, and R 2 represents a hydrocarbon group having 1 to 10 carbon atoms.) An olefin polymerization catalyst is used from an organosilicon compound represented by the formula: |
