Abstract:

A trifluoromethyl-activated dichloro-monomer was synthesized via a two-step procedure including a formation of (4-chloro-3-trifluoromethyl)phenyldiazonium chloride and a coupling reaction. Derived from the dichloro-monomer, five fluorinated polyarylethers were prepared via a nucleophilic aromatic substitution polycondensation in the presence of K2CO3. The fluorinated polymers exhibited excellent thermal stability, and the temperatures at a 5% mass loss(Td,5%) of several polymers were above 500 ℃. A highly fluorinated polyarylether had strong hydrophobicity, judging by its contact angle of 104.7°. Also, these fluorine-containing polymers showed low refractive index and low dielectric constants. These highly-fluorinated polymers may be potential materials using as high-temperature coatings or thin films in optical and microelectronic fields.

Key words: Polyaryether, Fluorine-containing polymer, Solubility, Dielectric constant
