Can PVC Be Weakened by Bronsted-Lowry Acids Due to Chlorine Protonation?

[lapo3399]

Is it possible that PVC may have a weakness to Bronsted-Lowry acids as compared to other plastics, because of the ability of these acids to protonate the chlorine (because of chlorine's non-bonding electrons), therefore leading to bonding instability and vulnerability to attacks by water? Or is this totally wrong...

Thanks for your help!

As well: does anyone know whether a benzene side chain (such as the one in polystyrene) would be affected by Sulfuric acid? e.g. react to form poly(styrenesulfonic acid), or something else.

Thanks for your help!
