| titleOfInvention | A kind of catalytic component of olefin polymerization, preparation method and applications |
| abstract | The present invention relates to a kind of small-bore catalytic components and preparation method thereof for olefinic polymerization or combined polymerization.It is by being dissolved in magnesium halide in organic epoxy compound object, organic phosphorus compound and inert diluent, silane compound can also be added, form homogeneous solution, halide of titanium or derivatives thereof is reacted with gained homogeneous solution in the presence of precipitation additive, a kind of titanium ester type compound is added before the precipitation of solid material containing magnesium titanium is precipitated, precipitation of solid material loads on the precipitation of solid material after being formed or does not load electron donor, is obtained after being washed with inert diluent.The small-bore catalyst component particles surface is smooth, crackle is few, and average pore size is at 2 nanometers hereinafter, when for propylene polymerization and combined polymerization, and fine powder content is seldom in powder, is suitable for a variety of polymerization techniques such as slurry method, substance law and vapor phase method. |
