Document Type and Number:

WIPO Patent Application WO/2019/003853

Kind Code:

A1

Abstract:

A method for producing a solid catalyst for olefin (co)polymerization includes bringing into contact with each other a magnesium compound, a tetravalent titanium halide compound, an organic compound represented the following general formula (1) R1 k(C6H4-k)(COOR2)(COOR3) and an organic compound represented the following general formula (2) R4R5C=C (COOR6)(COOR7) wherein R1 is a halogen atom or an alkyl group, R2 and R3 are a linear aikyl group, R4 and R5 are independently an atom or group selected from a hydrogen atom, halogen, a linear alkyl group, a branched alkyl group a vinyl group, a linear or branched alkenyl group, a cycloalkenyl group, an aromatic hydrocarbon group, and R6 and R7 are independently a linear alkyl group, a branched alkyl group, a vinyl group, a linear or branched alkenyl group a cycloalkyl group, a cycloalkenyl group, or an aromatic hydrocarbon group.
