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.

the cyano substituted N‐methoxyisoquinolinium salts 1.1 and 1.4 are prepared. Their behaviour in the presence of O‐, C‐ and N‐nucleophiles in different aprotic solvents is examined: from the 1‐cyano substituted isoquinolinium derivative 1.1, 1‐ and 3‐animals or 1‐iminium salts are obtained depending on the amine used, and N‐methoxyisocarbostyril 4.1.1 in H2O and OH−. The reaction of the 4‐cyano‐N‐m
