Abstract:
An ansa bis(.mu.-substituted) Group 4 metal and aluminum metallocene compound corresponding to the formula: ##STR13## wherein: L' independently each occurrence is a .pi.-bonded group,M is a Group 4 metal,Z is a divalent bridging group causing the complex to have an ansa structure,X independently each occurrence is a Lewis basic ligand group able to form a .mu.-bridging ligand group, and optionally the two X groups may be joined together, andA' independently each occurrence is an aluminum containing Lewis acid compound that forms an adduct with the metal complex by means of the .mu.-bridging groups, and optionally two A' groups may be joined together thereby forming a single difunctional Lewis acid containing compound.
