INFLUENCE OF THE CONFORMATIONAL PARAMETERS ON PHYSICAL-PROPERTIES OF SOME POLYAMIDES CONTAINING PHENYLQUINOXALINE RINGS

Conformational parameters of some heterocyclic polyamides containing p henyl-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 solubil ity, glass transition temperature, initial decomposition temperature a nd dielectric constant have been studied with regard to the rigidity o f the chains of these polymers, and their relationships have been show n.
