Zusammenfassung:	A method of making foamed styrenic copolymer comprising reacting the styrenic copolymer with an ionomer to form a composition; and contacting a blowing agent with the composition to form the foamed styrenic polymer. An article formed from a composition comprising a styrenic copolymer, an ionomer and a blowing agent. L'invention concerne un procédé de fabrication d'un copolymère styrénique expansé comprenant la réaction du copolymère styrénique avec un ionomère pour former une composition ; et la mise en contact d'un agent gonflant avec la composition pour former le polymère styrénique expansé. L'invention concerne également un article formé à partir d'une composition comprenant un copolymère styrénique, un ionomère et un agent gonflant.
