Abstract: Propylene polymers (I), containing (a) 50-95 pts. wt.propylene homopolymer with an MFI 230/2.16 (ISO 1133) of 0.1-100 g/10 mins. and an isotacticity of at least 98%, (b) 5-50 pts. wt. ethylene copolymer with a density of 0.865-0.920 g/cm containing 4-40 wt% 4-20C alkene-1 units, and (c) 0-1.5 pts. wt. nucleating agent, in which the total amount of (a) + (b) = 100 pts. wt. Also claimed is a process for the production of (I) by compounding the components at 200-250 degrees C in a mixing apparatus, preferably an extruder.
