Abstract
A process for producing an olefin copolymerization catalyst, comprising the step of contacting, with one another, (A) a solid catalyst component containing a titanium atom, a magnesium atom and a halogen atom, (B) an organoaluminum compound and/or organoaluminumoxy compound, and (C) a nitrogen-containing aromatic heterocyclic compound, whose one or more carbon atoms adjacent to its nitrogen atom are linked to an electron-withdrawing group, or a group containing an electron-withdrawing group; and a process for producing an olefin copolymer using the an olefin copolymerization catalyst.

A process for producing an olefin copolymerization catalyst, which comprises the step of contacting the following components (A), (B) and (C) with one another:
- (A) a solid catalyst component containing a trivalent titanium atom, a magnesium atom and a halogen atom;
- (B) an organoaluminum compound and/or organoaluminumoxy compound;
- and
- (C) a nitrogen-containing aromatic heterocyclic compound, whose one or more carbon atoms adjacent to the nitrogen atom are linked to an electron-withdrawing group, or to a group containing an electron-withdrawing group.
