Abstract: A process for reacting molten polyolefin with a free radical generator wherein the molten polyolefin passes through an extruder and free radical generator is mixed with the molten polyolefin in increments along the extruder such that any previously added free radical generator is decomposed before the next increment of free radical generator is added to the molten polyolefin. Products of the process demonstrate improved efficiency of free radical generator utilization as measured by enhanced melt flow rates relative to the total amount of free radical generator used.
