摘要： A solid titanium catalyst component (I) for olefin polymer production contains titanium, magnesium, halogen, and a cyclic multiple-ester-group-containing compound (a) represented by the formula (1). Preferably, a propylene polymer that is obtained by the olefin polymerization method and has specific thermal properties as determined primarily by differential scanning calorimetry (DSC).
