No, not when applying a small puddle in a depression and rubbing it
around. No softening, no stickyness, nothing, with my (european) denatured
alcohol. Vacuum formed polystyrene cups (white, solid no foam, for dairy
products) also show no reaction either. I believe they are also plain
polystyrene.
Seems a bit silly to me to denature it with something that dramatically
reduces it's applications. May be why IPA is used in the US instead.
