发明名称 METHOD FOR PRODUCING SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, CATALYST FOR OLEFIN POLYMERIZATION, AND OLEFIN POLYMERS
摘要 An environmentally-friendly solid catalyst component for olefin polymerization exhibits high hydrogen activity and high polymerization activity, can produce a polymer that exhibits a high MFR and high stereoregularity in high yield using a small amount of hydrogen, and exhibits high copolymerization activity and excellent copolymerization properties (e.g., block ratio). The solid catalyst component for olefin polymerization is produced by bringing (a) a magnesium compound, (b) an internal electron donor, and (c) a tetravalent-element halogen compound into contact with each other in an inert organic solvent, the internal electron donor (b) being represented by R 1 2 C(COOCH 3 ) 2 (wherein R 1 is selected from a branched alkyl group having 3 to 20 carbon atoms, a halogen atom, a linear or branched halogen-substituted alkyl group having 2 to 20 carbon atoms, a linear alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a vinyl group, and an allyl group).
