A polymer comprising from 5 to 16 wt% ethylene and from 84 to 95 wt% propylene, the polymer having:
a melting point by DSC of less than 105°C;
a heat of fusion < 75 J/g, as determined by DSC;
a crystallinity of from 2 to 65% of homoisotactic polypropylene, as measured by heat of fusion of annealed samples of the polymer;
a MWD from 2.0 to 3.2.
