Abstract
PURPOSE: To obtain the titled polymer with little formation of amorphous polymers and catalytic residues industrially and advantageously, by (co)polymerizing an α- olefin in the presence of a catalytic system consisting of a specific Mg-Ti solid catlyst and an organometallic compound activator.
CONSTITUTION: A ≥3C α-olefin is polymerized or copolymerized with a ≥2C olefin in the presence of a catalytic system consisting of (A) a solid catalyst obtained by bringing one g magnesium halide, e.g. MgCl2 or a reaction product of n-C4H9 MgCl with SiCl4 or AlCl3, if necessary with an electron donative compound, e.g. an amine, and then preferably 0.5W50ml p-substituted phenoxytitanium halide compound of the formula (OAr1 is p-substituted phenoxy; X is halogen; 0<n<1) at 0W150°C for 30min-3hr and (B) an organometallic compound activator of a metal selected from GroupsIWIII in the periodic table, e.g. (C2H5)3Al, at a molar ratio between Ti in the component (A) and component (B) of (2:1)W(1:600).
