Process for the production of polyolefins |
摘要 |
The present invention discloses improved catalysts for polymerizing or copolymerizing olefins and a process for the production of polyolefins comprising a polymerization or copolymerization of olefins by the use of said catalysts. According to the invention there is provided a process for the production of polyolefins by polymerizing or copolymerizing olefins using as the catalyst a solid component containing a titanium compound and/or a vanadium compound and an organometallic compound, said solid component comprising a substance obtained by co-pulverizing (1) a metal halide selected from the group consisting of magnesium halides and manganese halides, (2) a compound represented by the general formula Mg(OR)nX2-n in which n is a number of the range 0<n</=2, X represents a halogen atom and R is a hydrocarbon radical containing from 1 to 20 carbon atoms and may be alike or different and (3) a titanium compound and/or a vanadium compound.
