As the precursor of polyimide,polyamide acid was the key to synthesis of polyimide.By measuring intrinsic viscosity,the influences of charge sequence,momomer ratio,reaction time and reaction temperature on the intrinsic viscosity were discussed.The optimal technological conditions were confirmed,which provided basis for preparing high-temperature polyimide fiber.
