Process for preparation of solid component of catalyst for the (CO) polimerizacao of ethylene, solid component of catalyst.Catalyst for the (CO) polimerizacao of ethylene and process for ethylene (CO) polimerizacao

摘要

A solid component of a catalyst for the (co)polymerization of ethylene which comprises a silica carrier and a catalytically active portion including titanium, magnesium, chlorine and alkoxy groups is obtained by suspending activated silica in a solution of magnesium chloride and titanium tetraalcoholate in a liquid aliphatic acid ester; eliminating the aliphatic acid ester from the resulting suspension to recover a solid; and reacting the resulting solid with an alkyl aluminium chloride.
