Abstract

En polymeriseringskatalysatorbærerfremstilt ved sprøytekrystallisering Når det fremstilles partikkelformige bærere for olefin- polymerings-prokatalysatorer som omfatter en overgangs- metallforbindelse reagert på bæreren, er problemet å oppnå partikler, partikkelstørrelse, partikkelstørrelsesfordeling og partikkelform, dvs. morfologien, som er passende for disse. Disse problemene har blitt løst i foreliggende oppfinnelse gjennom en fremgangsmåte hvori: (a) det tilveiebringes en oppvarmet smelte av en kompleks forbindelse som har formelen I MgCl2 -nROH -mED (D hvori ROH står for en lavere (C^s) alifatisk alkohol, ED står for en elektrondonor, n er l til 6 og m er O til l, (b) den tilveiebrakte oppvarmete smelten mates til en dyse som atomiserer denne, (c) smelten som skal atomiseres sprøytes fra nevnte dyse inn i et kammer, hvor den fordeles i form av atomisert smelte og deretter størkner til fine bærerpartikler og (d) de fine bærerpartiklene utvinnes. Under denne fremgangsmåten tilføres et elektrisk felt inn i smelten som skal atomiseres eller har blitt atomisert, som reduserer overflatespenningen til den størknete smelten og forhindrer agglomerering av de dannete smådråpene. Ladningen kan tilføres ved å anordne en elektrode i forbindelse med dysen, som sammen med for eksempel den jordete smelten danner et statisk elektrisk par.
