Abstract:
1. A process for producing a solid titanium catalyst component (I) comprising titanium, magnesium, halogen and an ester compound which comprises: contacting a mixture of a magnesium compound (A) having no reducing ability in a liquid state and an ester compound (B) represented by the following formula (2) with a liquid titanium compound (C) to form a solid titanium composite, and then contacting the solid titanium composite with an ester compound (B1) represented by the formula (3), wherein the compound of formula (2) is: wherein n is an integer of 6, R R heteroatom, and or a, two or more R′ each are independently an atom or group selected from a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a halogen atom, a nitrogen-containing group, an oxygen-containing group, a phosphorus-containing group, a halogen-containing group and a silicon-containing group, and at least two of the two or more R′ may be bonded to each other to form a ring, and the skeleton of the ring formed with the two or more R′ may include a double bond or a heteroatom, wherein the compound of formula (3) is: wherein n is an integer of 5 to 10, R two or more R heteroatom, and or a, two or more R′ each are independently an atom or group selected from a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a halogen atom, a nitrogen-containing group, an oxygen-containing group, a phosphorus-containing group, a halogen-containing group and a silicon-containing group, and at least two of the two or more R′ may be bonded to each other to form a ring, and the skeleton of the ring formed with the two or more R′ may include a double bond or a heteroatom.
