Abstract

Fremgangsmåte for oppstarting av en gassfase-olefinpolymerisasjonsreaksjon utført ved bruk av en katalysator av Ztegler-Natta-typen basert på et overgangsmetall i en reaktor med fluidisert sjikt, gjennom hvilken passerer en reaksjonsgassblanding omfattende olefmen, en inert gass, hydrogen og eventuelt minst en komonomer og som arbeider under betingelser for temperatur og trykk som muliggjør oppstarting av polymerisa- sjonen, og denne fremgangsmåten er kjennetegnet ved at partialtrykket for olefmen og innføringshastigheten av katalysator inn i reaktoren økes mens forholdene for partial- trykkene for olefmen til hydrogenet og til den eventuelle komonomeren eller komonomerene opprettholdes vesentlig konstante.
