Abstract

PURPOSE: To suppres the formation of an amorphous polymer and obtain the titled polymer without the removing step of catalytic residues, by carrying out the (co) polymerization of an α-olefin in the presence of a catalyst prepared by incorporating a solid catalyst consisting of a magnesium halide and a specific titanium compound with a specific organometallic compound.
CONSTITUTION: (i) A magnesium halide, e.g. magnesium chloride, is subjected to the contact reaction with (ii) a titanium compound having a bond between titainum and an aryloxy group expressed by the formula -OAr (Ar is aryl) and a bond between the titanium and a halogen to prepare (A) a solid catalyst. A ≥3C α-olefin, e.g. propylene, alone polymerized or copolymerized with another ≥2C α-olefin, e.g. ethylene, in the presence of a catalytic system consisting of (A) the resultant solid catlayst and (B) an activator consisting of an organometallic compound of a metal selected from GroupsIWIII in the periodic table, e.g. triethylaluminum, to give the aimed polymer.
