The invention provides a supported chromium catalyst system comprising a chromium catalyst precursor bound via at least one heteroatom to a functionalised support, said heteroatom being connected to said support via an organic group.

Supported catalyst

The invention provides a catalyst system (preferably a heterogeneous catalyst system) comprising: a transition metal bisphenolate catalyst (preferably a group 4 to 6 transition metal bisphenolate catalyst) and another olefin polymerization catalyst, and optionally a co-catalyst, e.g. an organoaluminium compound or a boron compound.

Dual-site olefin polymerization catalyst composition

A supported titanium catalyst system comprising a titanium catalyst bound via at least one heteroatom, a functionalized support, said heteroatom being connected to said support via an organic group.
