Synthesis and characterization of polyimides from 9,10-dialkyloxy-1,2,3,4,5,6,7,8-octahydro-2,3,6,7-anthracenetetracarboxylic-2,3:6,7-dianhydrides and 4,4'-oxydianiline

Summary

New dianhydrides having alkyloxy side chains were synthesized and polymerized with 4,4'-oxydianiline in NMP. Chemically cyclized polyimides were obtained with inherent viscosities of 0.30∼0.84 dL/g range. All the polymers were highly soluble in polar solvent such as NMP at room temperature. TGA pyrograms showed two-step degradation and in DSC thermograms the polymers exhibited Tgs between 124°C and 259°C. Wide-angle X-ray diffractograms revealed very low crystallinity and layered structure, which was better developed in the polymers with longer side chains
