ABSTRACT:
A process for producing a class of polyarylenes having p-bis-(chlorodifluoromethyl) benzene or p-bis(bromodifluoromethyl) benzene as a comonomer. The p-bis-(chlorodifluoromethyl) benzene or the p-bis(bromodifluoromethyl)benzene act as precursors in a polycondensation reaction with a difunctional monomer.
