| Abstract
| - Recent studies have confirmed that model $\chem{C_{60}}$ has a stable liquid phase confined to a rather narrow temperature range; in this letter we determine the phase diagram of model $\chem{C_{70}}$ and show that also this fullerene possesses a liquid phase whose existence range is wider than that of $\chem{C_{60}}$. A "corresponding state"behaviour of $\chem{C_{60}}$ and $\chem{C_{70}}$, emerging from a description in terms of reduced quantities of both the interaction potential and the phase diagrams' parameters, is then extended to higher-order fullerenes. Critical- and triple-point densities and temperatures of $\chem{C_{76}}$, $\chem{C_{84}}$ and $\chem{C_{92}}$ are thereby predicted. The decreasing accuracy of such a representation of ${\rm C}_{n> 70}$ phase behaviour with increasing n is discussed in relation to the model potential features.
