ABSTRACT:
Solid polyolefin catalysts are adapted for use in low pressure gas phase fluid bed polymerization processes by being mixed with selected particulate organic support materials in a high speed bladed finishing device so as to cause the catalysts materials to become embedded in, and/or adhered to, softened particles of the support material.
