Aromatic polyimides are a class of high-performance polymers known for their excellent thermal stability, mechanical strength, and chemical resistance. They are widely used in applications such as electronics, aerospace, and automotive industries due to their ability to withstand extreme temperatures and harsh environments. These polymers are formed through the polycondensation of aromatic dianhydrides and diamines, resulting in a rigid molecular structure. Their unique properties make them suitable for insulating materials, flexible circuits, and high-temperature adhesives, contributing to advancements in technology and materials science.
