NEW MATERIAL: Compds. of formula I [wherein X is H, NO2 or NH2; Y is CH3, COOH, CONH2, NH, or -N=N-Z (in which Z is a group of formula II); with the proviso that when Y is -N=N-Z, X is NO2, and when Y is CH3, X is H].
EXAMPLE: 2-(3-Aminophenyl)-2-(4-aminophenyl)hexafluoropropane.
USE: Fluorine-contg. monomers for heat-resistant polycondensates such as polyamides and polyimides. The polymers are useful as commercial quality materials in aircraft and electronic industries.
PROCESS: 2-(4-Methylphenyl)hexafluoropropane-2-ol or 2- phenylhexafluoropropane-2-ol is condensed in the presence of hydrogen fluoride, then the product is oxidized, nitrated, reacted with amidosulfonic acid and then with an aqueous hypohalide soln., and reduced to obtain a compd. of formula I.
