We have synthesized 4,4'-dinitro-3 4''-dimethyl triphenylamine,(1), in 84% yield in an one-step condensation process between 3,4-dimethyl aniline and 4-fluoro-nitrobenzene. After the auto-oxidation of (1) and the subsequent hydrogenation of the nitro-groups, an AB2 type triphenylamine polyimide intermediate bearing two amine groups and one acid-anhydride group each on individual phenyl ring,{AB2 PI Intermediate}, was prepared successfully. The yields of the autoxidation and the hydrogenation steps are 81% and 90% respectively.

It was shown that the absorption peaks of amine and amide groups of gelatin were shifted in HDPE/PE-g-MAH/Gelatin blends because of the reaction of PE-g-MAH with gelatin. The addition of PE-g-MAH made the increase of HDPE glass transition temperature. The compatibilizing effect of PE-g-MAH was due to the crystal compatibility produced by forming the co-crystals of HDPE, PE-g-MAH and PE-g-MAH-g-gelatin. The blends of EAA and gelatin were prepared by melting process and the compatibility of the blends was also studied.

The blends of PE-g-MAH and gelatin were prepared by melting process and the compatibility of PE-g-MAH and gelatin in blends were characterized. The results of FTIR showed that the characteristic absorption band peaks of amine and amide groups of gelatin were shifted in PE-g-MAH/Gelatin blends, the equilibrium values of torque were higher with the increase of blending temperature, which proved that graft copolymer PE-g-MAH-g-gelatin was formed during the preparation process, and the amount of PE-g-MAH-g-gelatin was increased with increasing the amount of PE-g-MAH. SEM micrographs exhibited that there was PE-g-MAH-g-gelatin formed in surface of gelatin phase.
