Surface photostabilization of polystyrene by Tinuvin 1577

Bottino FA, Di Pasquale G, Pollicino A, Recca A

The effect of a new hydroxyphenyltriazine additive (Tinuvin 1577) on the surface photooxidation of polystyrene films at various concentrations of the additive was studied using ESCA spectroscopy. The accelerated weathering was run in a Xenotest apparatus to mimic outdoor conditions. The presence of Tinuvin 1577 effectively inhibited the surface photooxidation of polystyrene.
