Abstract: A propylene/ 1-hexene copolymer in which: i) the content of 1-hexene derived units, measured by C13-NMR, ranges from 1.5 wt% to 2.5 wt% and the content of propylene derived units ranges from 97.5 to 98.5 wt. %; ii) melting temperature measured by DSC in the range 148-153°C; iii) the amount of fraction insoluble in xylene at 25°C is higher than 97.0%; iv) has a melt flow rate (MFR) measured according to ISO 1133, 230°C, 2.16 kg ranging from 35 to 65 g/10 min. The copolymer is useful for the production of injection molded articles in particular Twin- Wall injection molding articles.
