Title:
MAGNESIUM HALIDE ADDUCT, OLEFINS POLYMERIZATION CATALYST COMPONENT AND CATALYST MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO/2007/112700
Kind Code:
A1
Abstract:
The component of magnesium halide adduct is represented by MgX2 mROH nE pH2O,in which X is chlorine, bromine,C1-C14alkoxy or aryloxy;R is C1-C12 alkyl,C3-C10 cycloalkyl or C6-C10 aryl; E is represented by the general formula (II), wherein R1 and R2 which can be the same or different to each other, are hydrogen or linear or branched C1-C10 hydrocarbon groups,C3-C10 cycloalkyl,C6-C10 aryl,C7-C10 alkaryl or aralkyl,optionally,the said aryl or alkylaryl or arylalkyl is substituted by one or more halogen in the aromatic ring,R1 and R2 can form ring or fused ring.R3and R4 have the same meaning of R1 and R2 except that they can't be hydrogen,m is 1-5,n is 0.005-1.0,and p is 0-0.8. Spherical catalyst component and catalyst made from the above spherical magnesium halide adduct and their use in polymerising the alpha-olefins CH2=CHR and their mixture are provided, in which R is hydrogen or C1-C12 alkyl or aryl.
