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.
