| titleOfInvention | It is a kind of for ball type carrier of olefin polymerization catalysis and preparation method thereof |
| abstract | The present invention relates to a kind of for ball type carrier of olefin polymerization catalysis and preparation method thereof.It the described method comprises the following steps：（1）In the presence of at least one macromolecular dispersion stabilizer, by magnesium halide and the organic compound reaction containing active hydrogen to form complex solution；（2）The complex solution and alkylene oxides compound are reacted, solid particle is separated out；（3）Reclaim the solid particle and obtain ball type carrier.When being used for propylene polymerization by catalyst prepared by ball type carrier of the present invention, with compared with high polymerization activity and higher stereotaxis ability. |
