Poly(Aryl Ethers) (PAEs) are high-molecular weight polymers that contain diphenyl ether links and can be synthesized by nucleophilic aromatic substitution (SNAr). In 1993, Hayes and coworkers demonstrated that alkynyl groups were sufficiently activating to allow for SNAr reactions. They also showed that bis-(4-fluorophenyl)acetylene (BFA) could react with bisphenols, such as bisphenol-A (BPA) to form acetylenic PAEs. My research looked at using bis(4-hydroxyphenyl)acetylene as a comonomer with BFA to form the PAE, poly(oxy-1,4-phenyleneethynylene-1,4-phenylene). The resulting PAE was reacted with aqueous acid to form a poly(aryl ether ketone) and with bromine to form a brominated PAE. Additionally, the potential for thermal crosslinking of the PAE’s triple bonds was investigated. The products were characterized by 1H NMR, C-13 NMR, and GPC-MALS.
