METHOD OF INTRODUCING SEVERAL CATALYSTS INTO SOLUTION Russian patent published in 2004 - IPC

Abstract RU 2233292 C2

FIELD: polymerization of olefins.

SUBSTANCE: proposed method includes introducing several catalysts into solution for polymerization reaction of olefins proceeding in gas phase reactor; at least two catalysts and at least one activator are introduced; each catalyst is activated independently; prior to introducing the activator and catalyst into reactor, they are combined in liquid carrier.

EFFECT: possibility of obtaining olefins at specific configuration.
