Abstract

Blandede katalysatorer som består av en første båret kromholdig katalysatorkomponent og en andre båret kromholdig katalysatorkomponent, og som dessuten inneholder ett eller flere metalliske eller ikke-metalliske katalytiske mid-ler. De ytterligere metalliske eller ikke-metalliske elementer som er asso-siert med katalysatorkomponentene, kan utgjøres av aluminium, titan, zirkonium, bor, fosfor eller kombinasjoner derav. Porevolumet i silikabærerne benyttet for den første og den andre katalysatorkomponent avviker fra hverandre.med minst 0,3 cm/g. De blandede katalysatorer ifølge oppfinnelsen er anvendelige for fremstilling av polyolefiner. De er sær-lig velegnede for partikkelformpolymeri-sering av etylen for fremstilling av polyetylenharpikser med høy densitet for formblåsing, som oppviser god bearbeid-barhet og gode fysikalske egenskaper. Den forbedrede partikkelformpolymerisa-sjonsprosess og produktene som oppnås ved denne under anvendelse av de ovenfor beskrevne blandede katalysatorer er likeledes beskrevet.
