| titleOfInvention | For ethylene homo conjunction or catalyst and its application of combined polymerization |
| abstract | The present invention provides the compositions and preparation method of a kind of carried catalyst and the catalyst for vinyl polymerization or combined polymerization, and wherein catalyst is grouped as by tri- groups of A, B, C.Wherein component A is that magnesium halide is dissolved in organic epoxy compound object, organic phosphorus compound, electron donor compound to form homogeneous solution, by TiCl 4 It is slowly reacted at low temperature with magnesium halide homogeneous solution, photocatalyst crystals is precipitated, then by strict control temperature reaction, and obtain catalytic component A, B component is organo-aluminum compound, the halogenated metallic compound of component C.When catalyst system of the invention is for ethylene homo conjunction or combined polymerization, higher catalytic activity is not only embodied, but also obtained polymer apparent density with higher, the molecular weight distribution of polymer are widened. |
