Phase diagrams long polymer chains

Figure 9 shows coexistence curves for polymers of 100, 600, 1000, and 2000 sites. The lines are the results of this work, and the open symbols are simulation data from the literature [25]. For n = 100 and n = 600, our results are in good agreement with literature reports. Note, however, that with the new method, we are able to explore the phase behavior of long polymer chains down to fairly low temperatures. The computational demands of the new method are relatively modest. For example, calculation of the full phase diagram for polymer chains of length 2000 required less than 5 days on a workstation. It is important to emphasize that, for the cubic lattice model adopted here, chains of 2000 segments correspond to polystyrene solutions... 

Eig. 9. Phase diagram for long polymer chains. The triangles are results reported by Pana-giotopoulos and Wong [25]. The curves show results of this work. Note that with the HPTMC, we are able to calculate the phase diagram for longer polymers, down to lower temperatures, with modest computational requirements.
