Catalyst for the polymerization of olefines and processes for the polymerization of olefines using the same |
摘要 |
<p>A catalyst for the polymerization of olefines comprises a solid catalytic component obtained by pre-polymerizing propylene in the presence of (A) a solid component containing magnesium, titanium, halogen and an electron-donating compound, (B) an organic aluminium compound, and (C) an alkylalkoxysilane represented by the formula, R<1>Si(OR<2>)(OCH3)2, wherein R<1> represents a branched or cyclic alkyl group having 3 to 6 carbon atoms, and R<2> represents a branched alkyl, alkenyl or alkinyl group having 3 to 6 carbon atoms; (B) an organic aluminium compound; and (D) an alkyltrialkoxysilane represented by the formula, R<3>Si(OR<4>)2(OCH3), wherein R<3> represents a linear alkyl group having 3 to 6 carbon atoms, and R<4> represents a branched alkyl, alkenyl or alkinyl group having 3 to 5 carbon atoms.</p> |
