INCORPORATING ADDITIVES INTO MOLTEN POLYMER VIA SLURRY INJECTION UPSTREAM OF A HOPPER

Polymer additive(s) are injected into molten polymer upstream of the hopper that feeds a molten mix of polymer with incorporated polymer additive(s) to a polymer extruder. Additive incorporation into the molten polymer is facilitated by an inlet device positioned inside the hopper, where the inlet d...

Beschreibung
Zusammenfassung:	Polymer additive(s) are injected into molten polymer upstream of the hopper that feeds a molten mix of polymer with incorporated polymer additive(s) to a polymer extruder. Additive incorporation into the molten polymer is facilitated by an inlet device positioned inside the hopper, where the inlet device is configured to: i) receive a feed stream comprising a molten polymer, a liquid diluent, a polymer additive, and unreacted monomer, ii) provide one or more solid surfaces for incorporating the polymer additive into the molten polymer, and iii) direct the molten polymer and the polymer additive into the molten polymer pool that is in the hopper.
