A new method for preparing aromatic polyamide-polyimide random copolymer films has been developed. Oxydianiline, pyromellitic dianhydride, and terephthaloyl chloride were evaporated separately from thermostatically controlled pulse molecular evaporation sources, which were actuated by solenoid valves, producing a polyimide-polyamide film after curing treatment. By selecting the appropriate combination of monomers, other copolymer films could be obtained through the sequential vacuum deposition polymerization process.
