碩士 === 國立臺灣科技大學 === 纖維及高分子工程系 === 89 === This study of thermally-stable , tough , linear polyimides containing amide linkages were prepared . The aromatic polyamide-imides were prepared by reacting a group of diamine with PMDA (Pyromellitic dianhydride)and DSDA (3,3’,4,4’-Diphenylsulfone tetracarboxylic dianhydride) to from thepolyamide-acid (PAA) with subsequent thermal conversion to the polyamide-imide (PAI) . These polymers has high dynamic viscosities up to 100000~220000 cps .Moreover they also tested by TGA、DSC and universal testing instrument the thermal and mechanical properties. These aromatic PAI has glass trasition temperatures in the range of 336~371℃ . The films showed good thermal stability and tesistance to organic solvent .
