Abstract:
1. A process for producing a magnesium compound-supported nonmetallocene catalyst, which comprises: a contacting step of contacting a magnesium compound with one of the two: a chemical treating agent and a nonmetallocene ligand to obtain a resultant mixture, upon finish of the reaction, the resultant mixture is subjected to filtration and washing, or to filtration, washing and drying, to obtain a contact resultant, wherein the chemical treating agent is a Group IVB metal compound; and a treating step of treating the contact resultant with the other of the two: the chemical treating agent and the nonmetallocene ligand, so as to obtain the magnesium compound-supported nonmetallocene catalyst, wherein the nonmetallocene ligand is a compound having the following structure: wherein: q is 0 or 1; d is 0 or 1; A is selected from the group consisting of an oxygen atom, a sulfur atom, a selenium atom, —NR 23 R 24 , —N(O)R 25 R 26 , —PR 28 R 29 , —P(O)R 30 OR 31 , a sulfone group, a sulfoxide group and —Se(O)R 39 ; B is selected from the group consisting of a nitrogen-containing group, a phosphor-containing group, and a C D is selected from the group consisting of an oxygen atom, a sulfur atom, a selenium atom, a nitrogen-containing C —N(O)R 25 R 26 , and —P(O)R 32 (OR 33 ), wherein N, O, S, Se and P each represent a coordination atom; E is selected from the group consisting of a nitrogen-containing group, an oxygen-containing group, a sulfur-containing group, a selenium-containing group and a phosphor-containing group, wherein N, O, S, Se and P each represent a coordination atom; G is selected from the group consisting of a C → represents a single bond or a double bond; — represents a covalent bond or an ionic bond; R
