Abstract
Polyimides (PI) having different molecular weights were prepared by co ndensation of oxydiphthalic anhydride with 9,9-bis-(4-aminophenyl)fluo rene in nitrobenzene solution at 180 degrees C. These polyimides carri ed two amino chain ends which allowed us to fix polycaprolactam chains (PA6) to obtain PA6-PI-PA6 type copolymers. The elemental analysis an d infrared spectroscopic determination gave the proportion of PA6 (or PI) in the copolymers. The studies of thermal properties -DSC and TGA- allowed us to characterize the copolymers.
