摘要:
A novel fluorine-containing aromatic compound of the formula: ##STR1## wherein X is ##STR2## in which R.sub.f is a perfluoroalkyl group having 1 to 10 carbon atoms,R.sub.f ' is a perfluoroalkyl group having 1 to 12 carbon atoms,p is an integer of 1 to 3,q is an integer of 0 to 3,r is 0 or 1,s is an integer of 0 to 5and t is an integer of 0 to 5,Y is X, a hydrogen atom, an alkyl group having 1 to 8 carbon atoms or a fluoroalkyl group having 1 to 8 carbon atoms, andeach A is independently ##STR3## in which D is an amino, carboxyl, hydroxyl, methyl or haloformyl group, and n is an integer of 1 or 2, or ##STR4## can be used to derive various compounds, some of which are useful for preparing a fluorine-containing epoxy compound of polyimide with good properties.
