| abstract | (57) [Summary] (Correction) [Problem] Propylene polymer with improved rigidity and heat resistance, high hardness, and excellent fatigue properties, wear resistance, dimensional stability, chemical resistance, and moldability. Provision of coalescence. SOLUTION: MFR (ASTM-D1238) is 5 < MFR <100, residual amount (HI, wt%) after extraction with boiling n-heptane exceeds 90, 200 ° C The frequency ω p and the MFR obtained from the dynamic melt viscoelasticity at the following equation are log (ω p ) <0.966 · log (MFR) −0. In the presence of a crystalline polypropylene satisfying the relation of 436 and a catalyst consisting of a solid component (A) and an organoaluminum compound component (B) containing magnesium, titanium, a halogen and an electron donating compound as essential components, propylene is polymerized. In the case of prepolymerization, the polypropylene further comprises the organosilicon compound component (C) of (1) in combination during prepolymerization and / or main polymerization, or when not prepolymerized, during main polymerization. Crystalline polypropylene obtained by R 1 Si (OR 2) x (OR 3) y ··· (1) ( a hydrocarbon group of C 1 ~ 10) |
