Group 4 transition metal complexes of bidentate iminonaphthol pro-ligands can be used as catalysts to polymerise olefins, such as ethylene. Group 4 transition metal complexes of bidentate iminonaphthol pro-ligands can have a single-site nature, allowing the catalysts to be used to prepare ultra high molecular weight polyethylene having a narrow molecular weight distribution.

A process may include contacting an olefin monomer and a racemic bridged metallocene catalyst at a temperature of 80 C. to 150 C. in the presence of hydrogen. The racemic bridged metallocene catalyst may include a metallocene compound (A) and an activator component (B). The process may include recovering an effluent containing polyalpha-olefins (PAOs). The metallocene compound (A) may be represented by the formula R(Cp
