SYNTHESIS, CHARACTERIZATION AND FILM PREPARATION OF NEW CO-POLYIMIDE BASED ON NEW 3,5-DIAMINO- N -(PYRIDIN-4-YLMETHYL)BENZAMIDE, ODA AND 6FDA

ABSTRACT This work describes mainly the synthesis and characterization of new co-polyimides obtained from the polycondensation of the dianhydride 4,4′-(hexafluoroisopropylidene)diphthalic anhydride (6FDA), 4,4′-oxydianiline (ODA) and the new diamine 3,5-diamino- N -(pyridin-4-ylm...
