A polymer comprising from 5 to 16 wt% ethylene and from 84 to 95 wt% propylene, and a diene in an amount no greater than 10 wt%, the polymer having: n na melting point by DSC of less than 105°C; na heat of fusion of at least 75 J/g, as determined by DSC; na crystallinity of from 2 to 65% of homoisotactic polypropylene, as measured by heat of fusion of annealed samples of the polymer; na MWD from 2.0 to 3.2. |
