Patent ID: 11981761

Abstract:
Process for reducing the volatile organic compound content of 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.); to below 65 ppm (VOC, VDA277), the process comprising the steps of a) providing raw plastomer in granular form, the 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, and the granules having an average D50 diameter of 2.5 to 4.5 mm b) subjecting said granular raw plastomer to at least one intensive hydrodynamic regime at a minimum temperature of at least 20° C. and a maximum temperature of 4° C. below the Vicat temperature (10 N, ISO 306) of the granular raw plastomer or 35° C., whatever value is lower, with the temperature measured at the gas inlet to the fast-fluidization regime, c) recovering the granular plastomer.
