Polyimide containing 4,4'-bis(4-amino-2-trifluoromethylphenoxy)- biphenyl moieties

摘要

Polyimides useful in multilayer electronic devices containing the 4,4'- bis(4-amino-2-trifluoromethylphenoxy) biphenyl moiety have low dielectric constants, low moisture uptake, high thermal degradation stability, low glass transition temperature.
