| Abstract: | A molecular thermodynamic model for homopolymer and copolymer systems with association segments was established by adopting the molecular thermodynamic model for hardsphere‐chain fluid as a reference, a perturbation term contributed by the square‐well potential and a contribution of association terms. The latter considers the multi‐associated‐segments in a chain‐like molecule based on the shield‐sticky model of chemical association. The model can be used to correlate the pVT of melten homopolymer and copolymer. Good agreements with experimental data have been obtained. |
