Summary: | In an embodiment, a method of dewatering a wet polymer composition comprises introducing the wet polymer composition via a polymer feed location to a powder conveying section of an extruder; wherein the wet polymer composition comprises greater than or equal to 1 wt % of water based on the total weight of the wet polymer composition; venting the water through a conveying section vent to form a dry polymer composition; melt kneading the dry polymer composition in a melt kneading section of the extruder to form a polymer melt; conveying the polymer melt in a melt conveying section of the extruder; and adding an additive in one or both of the powder conveying section and the melt conveying section. |
