Abstract
Disclosed is a propylene polymer composition comprising (A4) 50-97 wt.% of a propylene polymer which is prepared by polymerizing propylene in the presence of a catalyst comprising (d) a solid titanium component and (e) an organometallic component and has a melt flow rate (MFR) of 0.01-50 g/10 min., a molecular weight distribution (Mw/Mn) of 4-15 and a crystallinity of not less than 50% and (C) 50-3 wt.% of an ethylene/olefin random copolymer which is prepared by polymerizing 20-80 mol% of ethylene and C3-20.alpha.-olefin in the presence of a catalyst comprising (i) a Group IVB transition metal compound containing a ligand having a cyclopentadienyl skeleton and (ii) an organoaluminum oxy-compound or the like and has an intrinsic viscosity of 1.5-5 dl/g. The propylene polymer composition may be used for producing molded articles.
