Fremgangsm}te for fremstilling av magnesiumoksydkloridpartikler med polyederstruktur, de oppn}dde partikler, et katalytisk preparat b}ret p} partiklene samt polyolefiner oppn}dd ved hjelp av det katalytiske preparat |
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. |
