Polyamides and polyimides containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents and their synthetic method are disclosed. Polyamide containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents is synthesized by reacting diamine compound (2,2-bis[4-(2-trifluoromethyl-4-aminophenoxy)-3,5-dimethylphenyl]propane) with an equimolar diacid via a polycondensation reaction. Polyimide containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents is synthesized by reacting diamine compound with an equimolar dianhydride via a polycondensation reaction. The novel polyamide and polyimide containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents are synthesized from the diamine compound containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents, wherein the polyamides and polyimides containing flexible isopropylidene, trifluoromethyl and tetramethyl substituents have appropriate thermal stability, mechanical properties, and processability.
