B) from 50 wt % to 81 wt % of a propylene ethylene 1-butene terpolymer having an ethylene derived units content ranging from 1.5 wt % to 6.0 wt % and 1-butene derived units content of between 4.8 wt % to 12.4 wt %;
the sum of the amount of component A) and B) being 100;
the composition being characterized by the following features: molecular weight distribution (MWD), expressed in terms of Mw/Mn, greater than 4.0; the creep and recovery curve measured on the polymer fuse at 200° C. shows a maximum value between 600 and 1200 seconds, lower than 53×10−5 1/Pa.
