Fluorinated Diamine and Polymer Formed Therefrom

摘要

There is provided a fluorine-containing diamine represented by formula (1). In this formula, R1 represents a condensed polycyclic type aromatic hydrocarbon group, and at least one -C(CF3)2OH group and at least one -NH2 group are in a relation such that they are attached to adjacent carbons of carbon atoms constituting the condensed polycyclic type aromatic hydrocarbon group. Polymer compounds derived from this fluorine-containing diamine have superior low dielectric property and low water-absorbing property, and, in addition to that, shows low thermal expansion property and high glass transition temperature.
