Abstract:
A process for the preparation of supported polymerization catalyst systems comprising the steps of:a) dissolving at least one transition metal complex in a mixture of at least two different solvents having different boiling points to form a solution, wherein said at least one of said at least two different solvents is a higher boiling point solvent having a boiling point greater than 150.degree. C. at room temperature and at atmospheric pressure,b) contacting said solution with at least one support material, the volume of the solution being sufficient to form a slurry with the support material(s), the volume of the higher-boiling solvent being less than or equal to the total pore volume of the support,c) removing more than 90% of the solvent having a lower boiling point; andd) adding at least one co-catalyst.
