Abstract:
The invention relates to a process for the preparation of a particulate ultra high molecular weight polyethylene (pUHMWPE copolymer, 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 ethylene and at least one olefinic co-monomer under polymerization conditions, wherein the organometallic compound is of the formula R33P═N—TiCpXn.
