Abstract

A process for producing a polypropylene using a compounding extruder includes a) a melting section including a first elongated cylindrical tube having a first inlet port to receive a propylene-based polymer and a first outlet port to discharge a first melt composition including a melt of the propylene-based polymer and a first screw arranged in the first elongated cylindrical tube to convey the propylene-based polymer to the first outlet port and b) a mixing section including a second elongated cylindrical tube having a second inlet port to receive the first melt composition, a second outlet port and a side inlet port between the second inlet and outlet ports to receive a further component, wherein the second outlet port is to discharge a second melt composition including the first melt composition and the further component and a second screw arranged in the second elongated cylindrical tube to convey the first melt composition and the further component to the second outlet.
