Molecular weight dependence of excluded volume effects is examined. The swollen-to-unperturbed coil transition point shifts to lower concentration range with increasing molecular weight (Mw). It is shown that in the limit of the infinite molecular weight, the excluded volume effects should vanish in all concentration range, except for the only one point, Co = 0. Quite in contrast, for short chains, the excluded volume effects never disappear even at the melt state.
