The present disclosure relates to a process for preparing a transition metal-Schiff base imine ligand complex. The process involves direct chelation of a Schiff base imine ligand by adding a transition metal halide in a halogenated fluid medium at a temperature in the range of 20 C. to 40 C. The process employs less hazardous reagents and mild reaction conditions to obtain the complex. The complex is efficient to be used as a catalyst for the production of disentangled ultra-high molecular weight polyethylene.
