  • Patent number: 11034784
    Abstract: A process for reducing the volatile organic compound content of granular plastomers having a density of equal to or lower than 883 kg/m3 and a MFR2 of 100.0 g/10 min or lower (ISO 1133 at 2.16 kg load and 190° C.), to below 65 ppm (VOC, VDA277), the process comprising the steps of providing a granular raw plastomer in a treatment vessel, the granular raw plastomer having a density of equal to or lower than 883 kg/m3, and a MFR2 of 100.0 g/10 min or lower (ISO 1133 at 2.16 kg load and 190° C.), and a volatile organic compound content (VOC, VDA277) of above 150 ppm, subjecting said granular raw plastomer to a gasflow within the range of 30 m3/(h t) to 150 m3/(h t) for an aeration time of less than 96 hours, whereby the gas has a minimum temperature of at least 26° C. measured at a gas inlet of the treatment vessel and a maximum temperature of 4° C. below the Vicat temperature (10 N, ISO 306) of the granular raw plastomer or 35° C.
    Type: Grant
