OLEFINPOLYMERISATIONSKATALYSATORER ANPASSADE FOER GASFAS PROCESSER, DERAS PREKURSOR, FRAMSTAELLNING OCH ANVAENDNING.

摘要

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.
