Abstract
Conformational parameters of some heterocyclic polymers containing phenyl-substituted quinoxaline units, phthalimide, 3,4,5,6-tetrachlorophthalimide or phenoxy groups, have been calculated by Monte Carlo method. Several physical properties such as solubility, glass transition temperature, initial decomposition temperature and dielectric constant are discussed in relation with the structure of the polymers and rigidity of their chains. The influence of each pendent group on the properties of the polymers was discussed. Keywords: conformational rigidity parameter, heterocyclic polymers, solubility, high thermal stability
