Abstract: |
|||
| A kind of ethylene polymerization catalyst,which is composed of A and B-a kind of alkyl aluminium,is high titanium load carriage.component A is a solid containing magnesium and titanium.First,when magnesium chlorite acted with butanol,we obtained the solvate of chloro magnesium-butanol after distillation.to remove load MgC12 and C4H9SiC13, where,the oxygen O has a bond to MgCl.Then,let this mixture load act with TiCl4 in order to make Ti combinated chemically into it.The component A contains Ti 9-12% (wt).This catalyst shows very high polymerization activity in usual polymerization conditions. | |||
