Novel flame retardant polyarylethers: synthesis and testing

Three new polyarylethers A–C based on bisphenol C and its derivatives have been synthesized and tested. These new polymers all show a glass transition temperature and are inherently flame resistant and do not require the use of any flame retardant synergist. The new polyarylethers can all be made in 2–3 steps from available raw materials, keeping cost to a minimum. The thermal and flame retardant properties, such as DSC and UL-94 rating, are examined.
