Abstract
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.
Claims17
A supported titanium catalyst system comprising a cocatalyst and a titanium catalyst directly bound via at least two heteroatoms to a functionalised support, said heteroatoms being connected to said support via at least one organic group, wherein said support has impregnated therein a polymerisation active metal complex.
A supported titanium catalyst system comprising a cocatalyst and a titanium catalyst directly bound via an oxygen atom to a functionalised support, said oxygen atom being connected to said support as part of a benzyl alcohol, ethylene glycol or 1,2-dihydroxyethylphenyl derivative.
A process for the preparation of a supported catalyst system comprising:
- (I) reacting a titanium catalyst precursor with a functionalised support in a solvent to bind said titanium catalyst precursor directly to said functionalised support via at least two heteroatoms attached to said support via at least one organic group;
- (II) impregnating said support with a polymerisation active metal complex;
- and
- (III) recovering a supported catalyst as a free-flowing solid or slurry.
