Abstract: A process includes contacting a metallic acrylic salt with a polyolefin, forming a polyolefin composition. The process includes extruding the polyolefin composition, and pelletizing the extruded polyolefin composition. A production rate of pellets of the polyolefin composition may be equal to or greater than a production rate of pellets of the polyolefin prior to contact with the metallic acrylic salt without increasing extrusion pressure or motor amperes. The polyolefin composition may have a melt flow rate that is lower than the melt flow rate of the polyolefin prior to contact with the metallic acrylic salt. The metallic acrylic salt may only be contacted with the polyolefin to form the polyolefin composition during a start-up of an extruder and pelletizer.
