The influence of conformational parameters on some physical properties of polyamides containing pendant acetoxybenzamide groups

Conformational parameters of some aromatic polyamides containing pendant acetoxybenzamide groups have been calculated by Monte Carlo method taking into consideration the hindered rotation produced by the side groups. Several physical properties such as solubility, glass transition temperature, initial decomposition temperature and dielectric constant were studied with regard to the rigidity of the chain of these polyamides. It has been shown that glass transition temperature is correlated with chain rigidity, whereas initial decomposition temperature and dielectric constant are not.
