—— | 3,3',5,5'-tetramethyl-2,2-bis[4-(2-trifluoromethyl-4-nitrophenoxy)phenyl]propane | —— | C33H28F6N2O6 | 662.586 |
PROBLEM TO BE SOLVED: To provide a method for readily and inexpensively preparing a polyamide and a polyimide which have solubility and are readily modified.
SOLUTION: The method for preparing a fluorinated polyamide having a flexible structure on a chain comprises using a diamine monomer and subjecting the compound, a condensing agent, different dioxides and different dianhydrides to direct polycondensation reaction to give a series of a new polyamide and polyimide containing fluorine. A polyamide having a structure represented by the formula is obtained by reacting various dicarboxylic acid monomers in the presence of calcium chloride, triphenyl phosphite, pyridine and N-methyl-2-pyridone at 130°C for three hours. A fluorinated polyimide is similarly obtained.
