Process for polymerization or copolymerizing olefins containing at least 3 carbon atoms |
摘要 |
A process for preparing a highly stereoregular olefin polymer or copolymer in high yield and with good reproducibility of quality and yield, which comprises polymerizing or copolymerizing an olefin containing at least 3 carbon atoms in the presence of a catalyst comprising (A) A SOLID TITANIUM CATALYST COMPONENT OBTAINED BY REACTING A SOLID MAGNESIUM COMPONENT WITH A TITANIUM COMPOUND IN THE ABSENCE OF A FREE ORGANOMETALLIC COMPOUND OF A METAL OF Groups I to III of the periodic table and separating the solid component of the resulting reaction product, said magnesium component being obtained by separating a solid from a suspension of a reaction product derived from (i) a magnesium dihalide, (ii) an active hydrogen-containing organic compound, (iii) an organic acid ester and (iv) an organometallic compound of a metal of Groups I to III of the periodic table, and (B) AN ORGANOMETALLIC COMPOUND OF A METAL OF Groups I to III of the periodic table.
