Abstract: A propylene, ethylene, 1-butene terpolymer made from or containing a) from about 1.8 wt % to about 5.9 wt % of ethylene derived units; and b) from about 2.0 wt % to about 4.5 wt % of 1 butene derived units; and having i) a ratio of C2 wt %/C4 wt % in the range from about 0.9 to about 1.3; wherein C2 wt % is the weight percent of ethylene derived units and C4 wt % is the weight percent of 1-butene derived units; ii) a Melt flow rate (determined according to ISO 1133 230° C., 2.16 kg) in the range from about 1.0 to about 30.0 g/10 min; and iii) a xylene soluble fraction at 25° C. between about 10 wt % and about 30 wt %. The weight percentages are based upon the total weight of the terpolymer.
