    • Spartan'06 gives a choice of two environments for optimizing the energy of chemicals: vacuum or water. We selected water, as we consider it a better model of the condensed phase in the polymer.

    • We determined a weight-averaged dielectric constant of the polymer environment during PEB to be 8. We used the dielectric constants of several solvents to represent the dielectric of polymers: 65% phenol at 9.8, 15% benzene at 2.3, 15% ethylacetate at 6.1, and 5% acetic acid at 6.2.
