Properties of Polystyrene

It is attacked by hydrocarbon solvents, has poor oxygen and UV resistance, and is rather brittle, i.e. it has poor impact strength due to the stiffness of the polymer backbone. Furthermore, its upper temperature limit for continual use is rather low due to the lack of crystallinity and its low glass transition temperature of about T g = 373 K (100°C).
