Abstract

En blanding som kan bli anvendt som katalysator for fremstilling av enalkenpolymer som har en multimodal molekylvektfordeling er tilveiebragt, som omfatter en overgangsmetallholdig katalysator, en metallocen og et borholdig organoaluminoksan, hvori hver komponent i blandingen er til stede i en effektiv mengde slik at et alkenpolymer som har en multimodal molekylvektfordeling kan fremstilles i ved å benytte blandingen som katalysator, ! fortrinnsvis i nærvær av en kokatalysator. Det er ; også tilveiebragt en fremgangsmåte til å fremstille ; blandingen som omfatter: (1) å bringe i kontakt en overgansmetallholdig katalysator med et organo- , aluminoksan disbergert i et oppløsningsmiddel til å | danne en slurry; (2) å kombinere slurrien med et boroksin for å fremstille en kombinasjon av en overgangsmetallholdig katalysator og borholdig organoaluminoksan; og (3) å bringe kombinasjon i kontakt med et metallocen. Videre er det tilveie- ; bragt en prosess for å polymerisere et alken for å fremstille et alkenpolymer ved å anvende blandingen.
