Реферат: "SOLID COMPONENT OF CATALYST FOR THE HOMO- AND CO-POLYMERIZATION OF ETHYLENE" Abstract A solid component of catalyst for the (co)polymerization of ethylene, including magnesium, halogen and titanium, is prepared: (i) by dissolving a magnesium dialkyl, a silicon halide and at times also an alkyl halide, in an inert organic solvent and maintaining contact until a granular solid precipitates; (ii) putting this granular solid in contact and making it react with a titanium halide, alkoxide or halogen-alkoxide, to produce a solid component of catalyst; and (iii)activating this solid component of catalyst by contact with aluminium alkyl halide, if a titanium alkoxide or halogen-alkoxide has been used in phase (ii).
Improved solid component of catalyst for the (co) polymerization of ethylene and process for its use
