Soluble aromatic polyimides with inherent viscosities of 0.23-0.50 dL/g have been synthesized from 2,2-bis ( 3-amino-4-hydroxyphenyl) hexafluoropropane (BAPAF) and various aromatic tetracarboxylic dianhydrides. Almost all polyimides were soluble in a wide range of organic solvents, i.e., acetone, m-

Various soluble polyimides with bis[4-(3-aminophenoxy)phenyl]sulfone and three kinds of dianhydrides were prepared in a polar N-methyl-2-pyrrolidone solvent by the traditional chemical two-step method. All the polymers synthesized had good solubilities in polar solvents and excellent thermal propert
## Abstract Soluble polyimides (PIs) were prepared as random or multiblock types with 4,4β²β(hexafluoroisopropylidene) diphthalic anhydride (6FDA) and 3,3β²,4,4β²βbiphenyltetracarboxylic dianhydride (__s__βBPDA) as acid dianhydride components and 4,4β²βbis(__m__βaminophenoxy) diphenyl sulfone (__m__βBA
