PURPOSE:To provide a polypropylene composition containing a nucleating agent, and having a high crystallization temperature, a high flexural elastic modulus and an excellent crystallinity, the nucleating agent not bleeding from the resin composition and not causing the coloration of the resin composition. CONSTITUTION:The subject composition comprises crystalline polypropylene and 0.05-10000wt.ppm, preferably 0.5-500wt.ppm, of a styrenic polymer which is produced by the polymerization of a styrenic monomer in the presence of a catalyst system comprising a transition metal complex and an organic aluminum compound, which has repeating units of the formula (R is H, alkyl, etc.) and whose stereoregularity is mainly a syndiotactic structure. |
