Abstract

PURPOSE: To obtain the titled high-purity polymer having improved stereoregularity, by using a catalyst obtained by blending titanium trichloride prepared by reducing titanium tetrachloride with metal aluminum followed by powdering with a specific organic Al component and a stabilized complex compound of organic phosphorus compound.
CONSTITUTION: (A) Titanium trichloride prepared by reducing titanium tetrachloride with metal aluminum followed by powdering is blended (B) an organic aluminum compound shown by the formula RR'AlX (R and R' are 1W18C alkyl or aralkyl; X is halogen atom) and a stable complex compound of organic phosphorus compound shown by the formula (R1O)(R2O)(R3O)P(R1,R2, and R3 are 1W18C hydrocarbon group) or the formula (R1O)(R2)(R3O) PO, to give a catalyst which is used for polymerizing α-olefin (e.g., propylene, etc.).
