A new polymer with low dielectric constant based on trifluoromethyl-substituted arene: preparation and properties

A polymer based on trifluoromethyl-substituted arene was synthesized with high molecular weight ( M n ) of 62 000 by the Scholl reaction. The polymer film showed low dielectric constants of about 2.56 in a range of frequencies from 1 to 25 MHz. Moreover, the polymer revealed high thermostability and good mechanical properties, suggesting that the polymer had potential applications in the electronics industry.
