UNDERSTOETTET OLEFINPOLYMERISASJONSKATALYSATOR, FREMGANGSMAATE FOR FREMSTILLING DERAV OG FREMGANGSMAATE FOR FREMSTILLING AV POLYMERER AV ETYLEN OG KOPOLYMERER AV ETYLEN OG ALFA-OLEFINER ELLER DI-OLEFINER

摘要

A process is described for the polymerisation of olefins in which a supported catalyst is used, which catalyst comprises a support and the product of the reaction of a metallocene of a metal in group 4b of the periodic table and an alumoxane, forming the product of the said reaction in the presence of the support.
