  • Process for producing monovinylaromatic polymer incorporating post-consumer recycled polystyrene, monovinylaromatic polymer incorporating post-consumer recycled polystyrene and articles produced thereof
    Patent number: 11692087
    Abstract: The invention relates to a process and an installation to produce a monovinylaromatic polymer (3) comprising post-consumer recycled polystyrene (PCR-PS) wherein the process comprises the steps of mixing the PCR-PS (5) and the monovinylaromatic monomer (7) within a dissolver (9) to dissolve the PCR-PS (5) in the monovinylaromatic monomer (7) so as to produce a polymerization mixture (13); and a step of filtering the polymerization mixture (13) that includes continuously redirecting at least a part of the stream of the filtered polymerization mixture (17) back to the dissolver (9) and mixing it with the polymerization mixture (13) so as to continuously reduce the content of insoluble material in the polymerization mixture (13) contained in the dissolver (9).
