description	A sheet material that includes an elastic component or material (e.g., film, nonwoven web laminated to the elastic component, etc.) is provided. The elastic component is formed from a styrenic block copolymer composition containing from about 10 wt. % to about 90 wt. % of styrene-butadiene-styrene block copolymer; and from about 10 wt % to about 90 wt. % of styrene-isoprene/butadiene-styrene block copolymer. The styrenic block copolymer composition has good viscosity stability during extrusion and thus may be readily formed into an elastic sheet material. The elastic sheet material may be subsequently crosslinked to achieve the desired elastic and mechanical properties. La présente invention concerne un matériau en feuille qui comprend un composant ou matériau élastique (par exemple, un film, une bande non-tissée laminée sur le composant élastique, etc.). Le composant élastique est formé d'une composition de copolymère séquencé styrénique contenant d'environ 10 % en poids à environ 90 % en poids de copolymère séquencé styrène-butadiène-styrène ; et d'environ 10 % en poids à environ 90 % en poids de copolymère séquencé styrène-isoprène/butadiène-styrène. La composition de copolymère séquencé styrénique a une bonne stabilité de viscosité pendant l'extrusion et peut donc être aisément formée dans un matériau de feuille élastique. Le matériau de feuille élastique peut ensuite être réticulé pour obtenir les propriétés élastiques et mécaniques souhaitées.
