抄録

Direct aromatic fluoroalkylation of polyimide, 6FDA-BAPF [_??_], was found to proceed by use of bis (fluoroalkanoyl) peroxides [ (RFCO2) 2, RF=C3F7, C6F13, C7F15, (CF2) 6H] under very mild conditions. The reduction in molecular weight of fluoroalkylated 6FDA-BAPF [6FDA-BAPF-RF] indicated that the imide groups in the polymer were hydrolyzed with fluoroalkanoic acids which are produced as the by-products of the fluoroalkylation. Furthermore, it was clarified that the Tg value of 6FDA-BAPF-RF was decreased, whereas the dielectric constant of 6FDA-BAPF-RF increased by the fluoroalkylation.
