Abstract

Gradient copolymers have been synthesized and used to compatibilize immiscible blends of polystyrene (PS) and polyethylene oxide (PEO) produced by conventional melt processing. Blends with a dispersed phase size of ∼100 nm are formed and are stable when statically annealed. These nanostructured blends can exhibit unique thermal behavior, such as PEO nanodomains crystallizing at a temperature 60 °C below the bulk crystallization temperature. The gradient copolymer sequence distribution plays a large role in the efficacy of compatibilizaton.
