Abstract: Described here are blocky PEEK copolymers and corresponding synthesis methods. It was surprisingly found that synthesis of blocky PEEK copolymers in a non-solvent environment with respect to PEEK produced blocky PEEK copolymers with high degrees of functionalization and crystallinity. The blocky PEEK copolymers had an increased blocky structure, relative to corresponding PEEK copolymer synthesized with other known methods. Moreover, membranes formed from the blocky PEEK polymers are particularly desirable in fuel cell applications. For example, the membranes formed from the blocky PEEK polymers had surprisingly large ion conductivities as well as significantly improved chemical and thermal resistance, at least in part, to the improved functionalization and crystallinity.
