Beschreibung
Zusammenfassung:	A process for the purification of a feedstock resulting from a process for the depolymerization of styrene compounds, referred to as feedstock of the purification process, comprises at least a separation step producing an extract rich in light compounds, a raffinate rich in heavy compounds and a stream rich in styrene, and a step of separation of the stream rich in styrene into at least a stream comprising predominantly ethylbenzene, a stream comprising predominantly styrene and a stream of heavy compounds.
