Propylene polymer blends containing a) a propylene homopolymer having a melt flow index of from 0.001 to 5 g/10 min, as determined at 230 DEG C. under a load of 2.16 kg, b) a propylene/ethylene copolymer having an ethylene content of from 5 to 80% w/w, and c) a propylene homopolymer having a melt flow index of from 1 to 104 g/10 min, as determined at 230 DEG C. under a load of 2.16 kg, the ratio of the melt flow index of the propylene homopolymer c) to that of the propylene homopolymer a) being within the range 10:1 to 107:1. The blends of the invention are high-flow materials showing a broad molecular weight distribution, and are thus readily processible.
