description Polymer compositions may include a matrix phase comprising a polypropylene-based polymer; and an elastomeric rubber phase; wherein the polymer composition has melt flow rate (MFR) according to ASTM D1238 at 230° C./2.16 kg equal to or greater than 90 g/10 min and at least one feature selected from (I) an Izod impact resistance according to ASTM D256A at 23° C. equal to or greater than 400 J/m; (II) an instrumented drop impact at −30° C., average total energy, equal to or greater than 17 J; or (III) an instrumented drop impact at −30° C., average percent ductility, equal to or greater than 60%.
