Polystyrenes (PS) are polymers mainly consisting of styrene units. Among the , isotactic, and polystyrenes are known, but only the latter, the so-called standard polystyrene, and the syndiotactic version are of economic importance. Copolymers with a high degree of styrene units are also considered polystyrenes. Of considerable economic importance are copolymers with butadiene which as significantly improves the of polystyrene.
