The homo-polymerization of propylene is carried out in the presence of a catalyst comprising a solid catalyst component (I), wherein the solid catalyst component (I) comprises titanium, magnesium, a halogen, a carbonate compound represented by the formula: R1-O-C(=O)-O-Z-O-R2 (1) (wherein R1 and R2 independently represent a hydrocarbon group or a substituted hydrocarbon group each having 1 to 24 carbon atoms or a group containing a hetero atom and may be the same as or different from each other; and Z represents a bondable group that can be bonded through a carbon atom or a carbon chain) and a diether compound. In this case, the catalyst can exhibit high stereoregularity and highly active catalytic performance, has good hydrogen responsiveness, and exhibits excellent polymerization behavior in random copolymerization or block copolymerization. |
