US Patent No: 9464175

Melt devolatilization extrusion processs

---

Abstract

---

Brominated organic polymer solutions from a bromination reaction are devolatilized in a devolatilizing extruder. A starting organic polymer is brominated in solution to form a brominated polymer solution. This solution is combined with a second thermoplastic polymer to form a concentrated solution. The solvent and other volatile compounds are removed from the concentrated solution in a devolatilizing extruder to form a devolatilized polymer blend.
