Abstract: | Summary New polyarylene ether ketones and polyarylene ether sulfones were prepared by polycondensation of various bisphenols with two new dihalide monomers including dibenzofuran structure, respectively 3,6 bis (4-fluorophenylcarbonyl) dibenzofuran and 3,6 bis (4-fluorophenylsulfonyl) dibenzofuran. Most of these thermoplastic polyethers are soluble in NMP and in chlorinated soluents. They exhibit Tgs up to 234°C for the polyetherketones and up to 262°C for the polysulfones, so over 50°C higher than the Tgs of classical available polyethers. |
