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 catalyst 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 slolid catalyst obtained by bringing one g magnesium halide, e.g. MgCl2 or a reaction product of n-C4H9 Cl with SiCl4 or AlCl3, into contact with if necessary an electron donative compoud, e.g. an amine, and preferably 0.5W50ml m-substituted phenoxytitanium halide of the formula (OAr3 is m-substituted phenoxy; X is halogen; 0<n<1) at 0W150°C for 30minW3hr and (B) an organometallic compound activator, e.g. (C2H5)3Al, of a metal selected from GroupsIWIII in the periodic table at a molar ratio between Ti in the component (A) and the component (B) of (2:1)W(1:600).
