    • w, which was perturbed by the intramolecular excluded-volume effect. The theory for the wormlike touched-beads model which is more suitable for short flexible chains, can be equally satisfactorily fitted to [η] of PPP in cyclohexane.

    • The same MD calculations were also done for cis-transoidal PCPA. However, intramolecular hydrogen-bonding between the neighboring carboxy groups of PCPA was formed during the calculations at 300 K, and therefore, exact fluctuation could not be estimated at 300 K.
