Long carbon fibre reinforced polypropylene composition

A process for reducing the volatile organic compound content of granular plastomers having a density of equal to or lower than 883 kg/mand a MFRof 100.0 g/10 min or lower (ISO 1133 at 2.16 kg load and 190&#xb0; 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/m, and a MFRof 100.0 g/10 min or lower (ISO 1133 at 2.16 kg load and 190&#xb0; 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 m/(h t) to 150 m/(h t) for an aeration time of less than 96 hours, whereby the gas has a minimum temperature of at least 26&#xb0; C. measured at a gas inlet of the treatment vessel and a maximum temperature of 4&#xb0; C. below the Vicat temperature (10 N, ISO 306) of the granular raw plastomer or 35&#xb0; C. measured at the gas inlet of the treatment vessel, whatever value is lower; and recovering the granular plastomer.
