摘要：
Poly(phenylquinoxaline-imide-amide)s have been synthesized by solution polycondensation of aromatic diamines containing preformed phenylquinoxaline rings with a diacid chloride incorporating preformed imide rings and hexafluoroisopropylidene (6F) groups. These polymers do not decompose up to 400 degrees C and have glass transition temperatures in the range of 284-308 degrees C. They are soluble in polar amidic solvents, such as N-methyl-pyrrolidone, and in less polar solvents such as pyridine and tetrahydrofuran, and give flexible films by casting from solutions.
