Influence of the Conformational Parameters on Physical Properties of Some Polyamides Containing Phenylquinoxaline Rings

Conformational parameters of some heterocyclic polyamides containing phenyl-substituted quinoxaline rings have been calculated by the Monte Carlo method taking into consideration the hindered rotation produced by the side phenyl groups. Several physical properties such as solubility, glass transition temperature, initial decomposition temperature and dielectric constant have been studied with regard to the rigidity of the chains of these polymers, and their relationships have been shown.
