Abstract: A nucleated propylene polymer composition comprising: A) from 77 wt% to 91 wt%, of a propylene homopolymer having a fraction insoluble in xylene at 25 °C higher than 95 %; B) from 9 wt % to 23 wt%, of a copolymer of propylene with from 28.0 wt% to 42.0 wt% of ethylene derived units; the composition having an intrinsic viscosity of the fraction soluble in xylene at 25 °C comprised between 1.0 dl/g and 1.9 dl/g, a fraction soluble in xylene at 25 °C comprised between 9.0 wt% and 21.0 wt%, a total melt flow rate (Melt Flow Rate according to ISO 1133, condition L, i.e. 230°C and 2.16 kg load) comprised between 1.5 and 5 g/10 min and the value of the relation (I): 22.5+0.2*MFR-1.2*Xs+0.2*IV is higher than 5.9; wherein MFR is the melt flow rate of the nucleated composition (Melt Flow Rate according to ISO 1133, condition L, i.e. 230°C and 2.16 kg load); IV is the intrinsic viscosity of the fraction soluble in xylene at 25 °C; and Xs is the fraction soluble in xylene at 25°C; wherein the amount of A+B is equal to 100 wt% and wherein the nucleated agent is selected from the group consisting of aromatic or aliphatic carboxylic acids, aromatic metal phosphates, sorbitol derivatives and talc.
