Various resins can be formed through imidization reaction of diaminodiphenyl oxide and other acids. Among the thermotolerant resins, the polyamide with fine performance can have continuous use temperature of up to 250°C.Depending on the requirement of small size, light weight, high reliability and long service time of electric equipment, and the application conditions of the equipment in the harsh environments of ocean engineering, space project, new energy resources technology, the much higher requirements are put forward for thermotolerant macromolecule insulating materials. Especially, the materials for thermotolerant macromolecule insulating membranes required for using in the semiconductor devices in recent years have enlivened the application area.
