| titleOfInvention | Optical communication polyimide and its manufacturing method |
| abstract | The present invention discloses an optical communication polyimide having a monomer represented by the formula (1) as a repeating unit, and a method of manufacturing the same.n n n n n n n n n n Wherein X 1 and X 2 are a halogen atom, a halogenated alkyl group, a halogenated aromatic ring group, NO 2 , -OR 1 or -SR 1 , wherein R 1 is halogenated alkyl or halogenated aromatic Ventilation); Z is a divalent halogenated aliphatic hydrocarbon, halogenated aliphatic ring hydrocarbon or halogenated aromatic hydrocarbon. Since the polyimide of the present invention can minimize light loss in the near infrared region, the polyimide can be very useful as an optical material in the optical communication field using light in the near infrared region. |
