A series of modified poly(ether ether ketone)s containing different content of benzene pendant group in the molecular chain have been successfully synthesized with 1,1-bis(4-hydroxyphenyl)-1-phenylethane, bisphenol A and 4,4′-difluorobenzophenone by nucleophilic substitution. The inherent viscosities of obtained polymers were in the range of 0.261–0.889 dLg−1. They were found to have high glass transition temperatures (Tg) of 150–168°C and 148–169°C (examined by DSC and DMA, respectively), good thermal stability with 5% weight-loss temperature (T5%) of 439–469°C. The tensile strengths of the obtained polymers were 67.7–86.6 MPa, and the storage modulus was over 0.9 GPa at about 140°C. The modified poly(ether ether ketone)s showed the excellent solubility property, they could be processed by solution method. Additionally, the obtained polymers had good optical transmittance (>70%) at 400 nm, suggesting that they have potential to be applied to the heat-resistant optical films.

“…Less reactive dichloro analogues often fail for this, partially because of the side reactions at such high temperature. However, high cost of difluoroaryl monomers, resulting in corresponding expensive polymers, pushes polymer chemists to develop the synthesis of poly(aryl ether ketone) from cheaper dichloroarylketone monomers, which is of industrial importance from a raw materials cost (RMC) point of view 3–5…”

As distinguished from the conventional preparation of poly(aryl ether ketone)s utilizing 4,4(-difluorobenzophenone, a novel synthetic method of high molecular weight poly(phthalazinone ether ketone) derived from 4,4(-dichlorobenzophenone was studied. Reaction conditions to get high molecular weight polymer were investi gated in details. Experimentally, sulfolane was chosen as the reaction media and high molecular weight polymer could be obtained in 7-8 hr at 210-C. The cyclic oligomers in the polymer product reduced to below 3.0% when the concentration of the reactant is 1.6-1.7 g/ml. Fourier transform infrared (FT-IR), 1 H NMR, and elemental analysis were used to confirm the structure of the obtained polymer. The amorphous polymer showed reasonable solubility in selective solvent, such as chloroform and N-methyl-2-pyrrolidone, and tough, flexible, and transparent thin film can be readily prepared from their N-methyl-2-pyrrolidone solution. The obtained polymer showed high glass transition temperature (T g ) up to 261-C detected by differential scanning calorimetry (DSC), and the temperature of 5% weight loss under nitrogen higher than 500-C detected by thermal gravimetric analysis (TGA), indicating its excellent thermal stability.

New homopolymers and copolymers based on aromatic polyethers bearing side diphosphonate and diphosphonic groups have been synthesized. These synthetic efforts resulted in homo and copolymers of high thermal stability but moderate molecular weights. To evaluate the influence of the immobilized phosphonate ester and phosphonic acid moieties on polymer electrolyte membranes for fuel cells applications, blends of the newly synthesized homo and copolymers with a pyridine‐based aromatic polyether were prepared. These blends were miscible with high glass transition temperatures and high thermal stabilities. Furthermore, the introduction of these groups to a polymeric backbone significantly increases the doping ability in phosphoric acid compared to the net matrix as well as the ionic conductivity for high doping levels. © 2010 Wiley Periodicals, Inc.
