Abstract

Oppfinnelsen vedrører en fremgangsmåte for fremstilling av en partikkelformig bærer for en olefInpolymerisa- sjonsprokatalysator innbefattende en omsatt overgangs- metallforbindelse som en bærer. Ved fremgangsmåten tilveiebringes et smelte-MgCl2-C2HgOH-kompleks inneholdende i gjennomsnitt 3,3 til 5,5 C2H5OH- molekyler pr. MgCl2-molekyl , smelte-MgC^-komplekset sprayes gjennom en dyse som dispergerer det i et kammer, hvori en partikkelformig bærer dannes av dette og den ferdige partikkelformige bæreren fjernes fra kammeret. I de hittil kjente fremgangsmåtene har det opptrådt problemer ved forsøket på å fremstille en bærer som har et optimalt C2H50H-innhold. Ved fore- liggende oppfinnelse har problemene blitt løst ved at man ved hjelp av varme fjerner så mye C2H50H fra MgCl2- C2H50H-komplekset i forbindelse med sprayingen at den oppnådde partikkelformige bæreren vil inneholde l gjennomsnitt 2,0 til 3,2 C2H5OH-molekyler pr. MgCl2- molekyl. En slik bærer har et velegnet C2H5OH-lnnhold og har en god morfologi , og det medfører ingen problemer å spraye denne.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a process for the preparation of a particulate carrier for an olefin polymerization procatalyst comprising a reacted transition metal compound as a carrier. In the process, a melt-MgCl2-C2HgOH complex containing an average of 3.3 to 5.5 C2H5OH molecules per The MgCl In the hitherto known methods, problems have arisen in the attempt to produce a carrier having an optimal C2H50H content. In the present invention, the problems have been solved by removing so much C 2 H 50 H from the MgCl 2 . MgCl2 molecule. Such a carrier has a suitable C 2 H 5 OH content and has a good morphology, and it causes no problems to spray it.
