ABSTRACT:
Described is a process for preparing low viscosity inorganic filler dispersions which comprises dispersing a large amount of finely divided inorganic filler compound as a slurry in a hydrocarbon diluent at all times in the presence of certain organoaluminum compounds. This process is particularly useful for preparing dispersions used in the preparation of polyolefin/inorganic filler compositions, especially polyolefin/inorganic filler compositions prepared in the presence of a catalytic transition metal compound.
