Novel methods for producing thermoplastic fluoropolymers
摘要:
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.
