New polymers which have wholly aromatic oligoamides as side chains were synthesized. Poly(N-phenyl acrylamide) (PPA) and poly(N-acryloyl-$ ho$-aminobenzanilide) (PBA) were prepared by the reaction of poly(acrylor chloride) with aniline and $ ho$-aminobenzanilide, respectively. The thermal properties of both polymers were examined by differnetial scanning calorimetry and thermogravimetry. It was found that PPA and PBA were in partly crystalline form, but no melting point could be detected. The Thermal property of the polymers was superior to that of poly(acrylic acid).
