Abstract
(EN)
A method comprising contacting a first styrenic polymer composition comprising residual styrene monomer with a molecular sieve, and recovering a second styrenic polymer composition comprising a reduced amount of residual styrene monomer A composition compπsing a styrenic polymer having a residual styrene monomer amount of less than 100 ppm produced by contacting a styrenic polymer composition having a residual styrene monomer amount of equal to or greater than 100 ppm with a molecular sieve, and recovering the styrenic polymer having a residual styrene monomer amount of less than 100 ppm A method comprising providing a styrenic polymer composition having a residual styrene monomer amount of equal to or greater than 100 ppm, contacting the styrenic polymer composition with a molecular sieve, adding a nucleating agent, a foaming agent, and a coloring agent, and forming an expanded styrenic polymer composition having a residual styrene monomer amount of less than 100 ppm

Méthode comprenant la mise en contact d'une première composition de polymère styrénique comprenant un monomère styrénique résiduel avec un tamis moléculaire, et la récupération d'une seconde composition de polymère styrénique comprenant une quantité réduite de monomère styrénique résiduel. La composition, comprenant un polymère styrénique à teneur en monomère styrénique résiduel inférieure à 100 ppm, est produite par mise en contact d'une composition de polymère styrénique ayant une teneur en monomère styrénique résiduel supérieure ou égale à 100 ppm avec un tamis moléculaire, et par récupération du polymère styrénique à teneur en monomère styrénique résiduel inférieure à 100 ppm. La méthode consiste à produire une composition de polymère styrénique à teneur en monomère styrénique résiduel supérieure ou égale à 100 ppm, mettre en contact la composition de polymère styrénique avec un tamis moléculaire, ajouter un agent de nucléation, un agent d'expansion et un agent colorant, et former une composition de polymère styrénique expansé à teneur en monomère styrénique résiduel inférieure à 100 ppm.
