Abstract:
1. A process for producing a supported nonmetallocene catalyst comprising dissolving at least one magnesium compound and at least one nonmetallocene ligand in the presence of at least one alcohol in at least one solvent to obtain a magnesium compound solution; drying the magnesium compound solution or introducing into the magnesium compound solution at least one precipitating agent to obtain a modified carrier; and treating the modified carrier with at least one chemical treating agent chosen from the group consisting of Group IVB metal compounds to obtain the supported nonmetallocene catalyst, and wherein the at least one nonmetallocene ligand is chosen from the group consisting of compounds having the following formula, wherein: q is 0 or 1; d is 1; 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; R
