摘要： Unsymmetrical metallocene compounds based on cyclopentadienyl ligands are disclosed, as well as catalytic compositions comprising the compounds supported on solid support materials. The compounds and compositions are useful as catalysts in the polymerisation of olefins. In particular, the compounds and compositions are useful catalysts in the preparation of low molecular weight polyethylene (e.g. polyethylene wax) and copolymers formed from the polymerisation of ethylene and other α-olefins.
