A novel titanium complex bearing 8‐anilino‐1‐naphthalenesulfonic acid was synthesized. The effects of cocatalyst and reaction conditions on ethylene polymerization were studied. The synthesized titanium complex exhibited high polymerization activity in the presence of MAO cocatalyst. The synthesized titanium complex/MAO catalyst system showed a uniform active site and was very stable at high polymerization temperature. In addition, the copolymerization of ethylene and norbornene was investigated. With the introduction of norbornene, the catalyst activity slightly decreased with MAO as cocatalyst but increased with TEA as cocatalyst. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
