    Abstract: 1. A polyolefin composition comprising: A) from 65 wt% to 85 wt%, of a propylene/ethylene/1-butene terpolymer wherein: i) the content of ethylene derived units ranges from 0.6 wt% to 2.5 wt; ii) the content of 1-butene derived units ranges from 6 wt% to 12 wt%; iii) the fraction soluble in xylene at 25°C ranges from 3.5 wt% to 20 wt%; B) from 15 wt% to 35 wt% of a propylene/ethylene copolymer having a content of ethylene derived units ranging from 10 wt% to 40 wt%; the copolymer optionally can contains 1-butene derived units in an amount less than 1 wt%; the sum A) + B) being 100.
