Abstract
PURPOSE: To obtain the title polymer having improved stereoregularity, by using a solid catalyst consisting of titanium tetrachloride supported on a carrier of a solid reaction product, prepared from an organomagnesium and a halogenated aluminum compounds, treated with an electron donor.
CONSTITUTION: An olefin is polymerized by using a catalyst system comprising of A) a solid catalyst consisting of titanium tetrachloride supported on a solid reaction product, prepared from an organomagnesium and a halogenated aluminum compounds (e.g., anhydrous aluminum chloride) shown by the formula R1 nAlX3-n (R1 is 1W8C hydrocarbon; X is halogen; 0≤n≤3), treated with an electron donor compound e.g., a carboxylate, B) an activator (e.g., triethyl aluminum) shown by the formula R2mAlY3-m (R2 is 1W8C aliphatic, alicyclic, and aromatic hydrocarbon; Y is halogen and 2<m≤3, or H and 2≤m≤3), and C) an electron donor compound, e.g., an ester.
EFFECT: High catalystic activity.
