The
sample with flocculated structure shows a "pseudo-solid-like" behavior which is a result of a large
solid volume fraction and high stress dissipation [5].

particularly, investigations have been performed on the crosslinked aromatic polyamides and
hetero cyclic polyamide material, the latter showed a high propensity of configuarational
changes (hydrogen bonding interaction1) within the molecular structure, as revealed through the
non monotonous temperature dependence of the annihilation rate constant (Fig 2).

Abstract.
Fig.2 The infrared spectroscopy of Polyaniline By a line shows, the characteristic absorption peaks of Benzene and Quinone ring from 1550cm-1 and 1650cm-1 move to 1543cm-1 and 1640cm-1 after doped with sulfosalicylic acid, it because doped make electron density decreased in polymer chain, reduces the force constant between atoms and produce inductive effect; at the same time, the delocalization effect increases about the efelectronic and electric charge in polymer chain as the role of doping, formation the resonance structure and produce conjugation.
