Abstract
Thermoplastic polyolefins (TPOs) and/or thermoplastic vulcanizates (TPVs) are blended with low molecular weight propylene-dominated copolymers to provide polymeric compositions with an improved balance between processability and toughness. The compositions have improved processability by facilitating the ease with which a TPO or TPV, usually difficult to melt process, can be processed at high line speeds, which in turn improves the formation of the composition into articles.
