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.

Melt devolatilization extrusion processs

Thermally sensitive polymers containing polymerizable carbon-carbon unsaturation and/or aliphatically bound halogen are devolatilized in a devolatilizing extruder. The thermally sensitive polymer is blended with a second polymer, which does not contain polymerizable carbon-carbon unsaturation or more than 5% by weight aliphatically bound halogen, and which has a molecular weight of from 25,000 to 175,000. The blend is then devolatilized in the extruder to produce a devolatilized polymer blend. Thermal degradation of the thermally sensitive polymer is minimized in this process.

Melt devolatilization extrusion process

Prepare a polymeric nanofoam using a continuous extrusion process by providing a polymer melt of a polymer composition in an extruder, introducing carbon dioxide to a concentration above the solubility in the polymer melt, cooling the polymer melt without increasing the pressure to achieve conditions where all of the carbon dioxide is soluble in the polymer composition and then extruding the polymer composition and carbon dioxide mixture through an extrusion die so as to experience a pressure drop of at least five MegaPascals at a rate of at least ten MegaPascals per second and allowing the polymer composition to expand into a polymeric nanofoam.
