Process for the preparation of high density ethylene polymers in fluid bed reactor. |
| 摘要 |
<p>A catalytic process for preparing ethylene polymers having a density of >/= 0.95 to </= 0.97 and a melt flow ratio of about >/= 22 to </= 32 in a low pressure gas phase process at a productivity of >/= 50,000 pounds of polymer per pound of Ti with a catalyst formed from selected organoaluminium as activator compounds and a precursor composition of the formula MgmTi1(OR)nXp[ED]q Wherein ED is a selected electron donor compound m is >/= 0.5 to </= 56 n is 0, 1 or 2 p is >/= 2 to </= 116 q = 1.5 m + 2 R is a C1 to C14 aliphatic or aromatic hydrocarbon radical, or COR min wherein R min is a C1 to C14 aliphatic or aromatic hydrocarbon radical, and X is selected from the group consisting of C1, Br, I or mixtures thereof, which catalyst is in particulate form and impregnated in a porous inert carrier material. The precursor impregnated with the carrier is not activated prior to charging it in the reactor.</p> |
