Abstract
Aniline-Formaldehyde polymer was synthesized by a new procedure ( as opposed to the conventional approach ). With an equal molar ratio of aniline and formaldehyde and a small amount of oxalic acid, the resulted polymer is free from gels and is suitable for fiber transformation.
The polymer is a transparent yellowish resin, having a melting range between 100-115C, and an average molecular weight 1200. The polymer was intended to be the precursor material for ion-exchange fibers. However, due to the time limit, this thesis only covers the work of polymer synthesis, fiber spinning and the identification of an crosslinker.
Among half an dozen of potential crosslinking agents, acetaldehyde has been singled out as the most effective crosslinker for the fiber spun from the polymer. The fiber has an tensile strength 21,000psi and elongation 11.4% and is suitable for further conversion into ion-exchangers.
