Hello,

I agree, that the difference connected with polymer structure is not known to current Geant4.

To be more precise: for today some molecular properties are used as corrections to various cross sections and stopping powers, namely mean ionisation potential, density effect corrections, ion/ion stopping powers. But this is possible only if these corrections are known and published. For this purpose internal DB on materials (Nist materials) was created. These material are accessed by the name of Geant4 NIST-materials. Number of electron/hole pairs per energy deposition may be added by user and be used in user actions. Other specific corrections to this material is not available so far.
