Titanium complex bearing 8‐anilino‐1‐naphthalenesulfonate ligand: Synthesis and catalytic behavior toward ethylene (co‐)polymerization

Abstract

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.

The renaissance of polyolefins

“…At the Journal of Applied Polymer Science, we are proud to feature daily on our pages the unfolding of this story, presenting new catalysts 5 for polyolefin synthesis, composites with biomaterials 6 and inorganic fillers such as clay, 7 polyolefin-based flame-retardants, 8 and novel extrusion techniques. 9 Amidst all this, the main drawback of these materials remains their long-term stability in the environment.…”
