Thermo-Reversible Gelation, Solvent-Extration/Aerogel Formation, and Reactions Thereof to Produce Non-Random Functionalization of Poly (Aryl Ether Keytones)

We have discovered a procedure to prepare a thermo-reversible gel of poly (ether ether ketone) (PEEK). These gels allow the formation of solvent-extracted aerogels of an engineering thermoplastic for high temperature insulation applications. Furthermore, these gels allow for the formation of functionalized PEEK bearing a non-random arrangement of the functional groups without disrupting the inherent crystallinity of the polymer. Sulfonated PEEK with high ion content and crystallinity is produced by this invention.
