| titleOfInvention | A kind of catalytic component for vinyl polymerization, catalyst and preparation method thereof |
| abstract | The present invention provides a kind of catalytic component for vinyl polymerization, it is that alcoholic compound and organic epoxy compound object formation homogeneous solution are dissolved in by magnesium halide, acts on obtaining with titanium compound in the presence of sulfur ester.When catalyst is used for vinyl polymerization at relatively high temperatures, higher polymerization activity, preferable hydrogen response and copolymerization performance, preferable bulk density are shown.Due to introducing sulfur ester, the particle shape of catalyst is improved, the hydrogen response and copolymerization performance of catalyst are improved；Simultaneously as the precipitation of precipitation need not be promoted using a large amount of titanium tetrachloride and titanium tetrachloride is used for multiple times to handle precipitation, causes the addition of titanium tetrachloride to greatly reduce, improve the production efficiency and benefit of catalyst. |
