Abstract
A polyamideimide for optical communications, having a minimum optical loss in a near infrared light wavelength range, high thermal resistance and good film processibility, and a method for preparing the same are provided. The polyamideimide is very useful as an optical material in the optical communications field adopting the light of near infrared light wavelength.
