Abstract:
1. A process for producing a supported nonmetallocene catalyst, comprising: dissolving at least one magnesium compound and at least one nonmetallocene complex in at least one solvent to obtain a magnesium compound solution; and drying the magnesium compound solution or mixing the magnesium compound solution with at least one precipitating agent to obtain the supported nonmetallocene catalyst, wherein the nonmetallocene complex is chosen from the group consisting of compounds having the following formula, wherein; q is 0 or 1; d is 1; m is 1, 2 or 3; M is chosen from the group consisting of Group III to XI metal atoms; n is 1, 2, 3 or 4; X is chosen from the group consisting of halogen atoms, a hydrogen atom, C A is chosen from the group consisting of an oxygen atom, a sulfur atom, a selenium atom, —NR 23 R 24 , —PR 28 R 29 , —P(O)R 30 OR 31 , sulfone groups, sulfoxide groups, and —Se(O)R 39 , wherein N, O, S, Se and P in A each represents a coordination atom; B is chosen from the group consisting of a nitrogen atom, nitrogen-containing groups, phosphor-containing groups, and C D is chosen from the group consisting of a nitrogen atom, an oxygen atom, a sulfur atom, a selenium atom, a phosphor atom, nitrogen-containing groups, phosphor-containing groups, C and —P(O)R 32 (OR 33 ), wherein N, O, S, Se and P in D each represents a coordination atom; E is chosen from the group consisting of nitrogen-containing groups, oxygen-containing groups, sulfur-containing groups, selenium-containing groups, phosphor-containing groups, and cyano groups, wherein N, O, S, Se and P in E each represents a coordination atom; G is chosen from the group consisting of C → represents a single bond or a double bond; — represents a covalent bond or an ionic bond; - - - represents a coordination bond, a covalent bond or an ionic bond; R
