Electrical resistivity of molten plastics 2

[Xabi33]

Hi could someone share any good articles or insights on how the electrical resistivity of common thermoplastics (PP, PET, PC, etc.) changes when they melt?

Generally it will go down - electron mobility increasing with temperature, etc.

I would guess PVC would drop significantly as it degrades at melt temperatures with HCl as a byproduct.

Politicians like to panic, they need activity. It is their substitute for achievement.
