Extruded polymer foams are made from a polymer composition that includes an unbrominated styrenic polymer, a brominated vinyl aromatic/butadiene flame retardant, and an unbrominated vinyl aromatic/butadiene polymer. The unbrominated vinyl aromatic/butadiene polymer improves the cell homogeneity. Mousses polymères extrudées produites à partir d'une composition polymère qui comprend un polymère styrénique non bromé, un retardateur de flamme vinyle aromatique/butadiène bromé, et un polymère vinyle aromatique/butadiène non bromé. Le polymère vinyle aromatique/butadiène bromé améliore l'homogénéité cellulaire.
