High-Energy Cryogenic Blending and Compatibilizing of Immiscible Polymers

Low-temperature mechanical alloying of immiscible polymers is investigated as a viable solid-state alternative to blending using melt or solution processes. The Figure is a schematic diagram of the alloying—or high-energy ball-milling—process, indicating that reactive chain coupling may occur in the event of free-radical generation due to chain scission.
