PREPARATION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE

摘要

The invention relates to a process for the preparation of a particulate ultra high molecular weight polyethylene (UHMWPE), comprising the steps of preparing a magnesium containing carrier, loading the carrier with a organometallic compound forming a supported catalyst and contacting the supported catalyst with at least ethylene under polymerization conditions, wherein the organometallic compound is of the formula R3 3P=N-TiCpXn.
