Process for de-polymerization of styrenic monomer-containing polymers and for retrieval of styrenic monomers

The invention relates to an improved process for providing purified styrenic monomers, such as styrene, from styrene-containing polymer waste. Styrene-containing waste is depolymerized in a suitable reactor, and the depolymerization products are condensed and separated in a three-step distillation p...
