Abstract：Conformational energies of the poly(tetramethylene oxide) chain in the third-order interac-tion approximation are calculated using semiempirical potential function method. Configuration-depen-dent properties of poly(tetramethylene oxide) chain, such as the characteristic ratio, the dipole momentratio and their temperature coefficients, are calculated using statistical weight matrix method based onthe rotational isomeric state(RIS) model. Results show that these values are better than those obtainedfrom the second-order interaction approximation, and the characteristic ratio and the dipole momentratio are in good agreement with experiment.
