Process for preparation of solid component of catalyst solid component of catalyst.Catalyst and process for polimerizacao terephthalate or Co polimerizacao of ethylene with alpha olefins
A solid component of a catalyst for the (co)polymerization of ethylene comprises a silica carrier and a catalytically active portion which includes titanium, magnesium, chlorine and alkoxy groups and is obtained by suspending an activated silica in an ethanolic solution of magnesium chloride; contacting the suspension with an alkoxide or halogen alkoxide of titanium and a silicon halide; eliminating the ethanol from the resulting suspension in order to recover a solid; and reacting said solid with an alkyl aluminum chloride.
