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. measured at the gas inlet of the treatment vessel, whatever value is lower; and recovering the granular plastomer.

Abstract: The invention relates to a process for the production of a foam having low organic compounds emissions, to polypropylene foamed products obtainable by the process, and to a process for the manufacture of low organic compounds emission articles comprising a foam for use in cars and food packaging. The process comprises the steps of: a) providing a foam comprising a propylene composition comprising a high melt strength propylene (HMS-PP) homopolymer or copolymer or combinations thereof, said HMS-PP foam having a melt strength of at least 25 cN at a maximum speed of at least 200 mm/s and a melting temperature of at least 135° C. and b) subjecting the HMS-PP foam to a thermal treatment at a temperature Tt which is preferably between 5 and 15° C. below the melting temperature Tm of the HMS-PP for a duration between preferably 1 and 10 minutes.
