Fluorinated polymaleimides with high thermal stability and low optical absorption loss in the optical communication wavelength of 1.55 µm were investigated for application in low-loss waveguide materials. The fluorinated polymaleimides were prepared from two monomers phenylmaleimide (H-PMI) and pentafluorophenylmaleimide (F-PMI). All synthesized copolymers had high thermal stability (decomposition temperature (Td)= 380-430 C). The ...
