概要
- 論文の詳細を見る
Polyimides were prepared from dianhydride with planar structure and Cardo-type or bulky-group-containing [-C(CF<SUB>3</SUB>)<SUB>2</SUB>-] diamines. Dense and flexibile flat membranes produced by the pyrolysis at relatively low temperature displayed high separation performance for C<SUB>3</SUB>H<SUB>6</SUB>/C<SUB>3</SUB>H<SUB>8</SUB> and CO<SUB>2</SUB>/N<SUB>2</SUB> gas pairs.
