Abstract
The use of a minor amount of poly-1-butene for improving the processability or extrusion efficiency of a metallocene-made thermoplastics, particularly metallocene-made low density polyethylene, by adding about 0.1-15 wt % of poly-1-butene to the metallocene-made thermoplastics which are melt incompatible with the poly-l-butene prior to processing.
