Abstract
The statistical weight parameters of poly(p-phenylene succinate) (PPSc) were determined by the best fit of Kθ which was determined by experiment, and found to be γ=1, σκ = 1.4, ση, = 1.4 and ωηκ = 0.1. The change of conformational entropy (◁Sconf) and enthalpy (◁Econf) of fusion, and the temperature dependence of unperturbed dimension of PPSc were calculated. Even though ◁Sconf of poly(ethylene terephthalate) (PET) and PPSc were close to each other, the ◁Econf of PET was positive but that of PPSc was negative. For the temperature dependence of unperturbed dimension, PET showed positive value contrary to negative value for PPSc.
