发明名称 |
Process for the preparation of magnesium chloride particles with polyhedral shape, magnesium chloride particles with polyhedral shape, catalytic composition supported on these particles, polyolefins obtained using these catalytic compositions and polypropylene particles having a macled crystal particle structure. |
摘要 |
Porous MgCl2 particles existing, under the microscope, in the form of substantially regular polyhedra having ten to eighteen faces. These particles, impregnated with transition metal compound, are used as catalytic component in the polymerisation of olefins. |
