    • The present invention relates to compositions such as fibers, elastic yarns, wovens, nonwovens, knitted fabrics, fine nets, and articles produced at least in part from a styrenic block copolymer comprising at least two blocks produced from vinyl aromatic monomers and at least one block produced from alkyl-substituted, conjugated alkene monomers, where the block produced from the conjugated alkene may have sufficient substitution so as to prevent or significantly minimize thermal cross-linking of the residual unsaturation in the formed block during fiber formation. Additionally, the composition may be described as processable, without requiring any additives if, for example, the order-disorder-transition (ODT) temperature is less than about 280° C.
    • 本发明涉及组合物,例如纤维,弹性纱,织物,无纺布,针织物,细网,以及至少部分由苯乙烯嵌段共聚物制备的制品,所述苯乙烯嵌段共聚物包含由乙烯基芳族单体和至少一个嵌段 由烷基取代的共轭烯单体制备,其中由共轭烯产生的嵌段可以具有足够的取代,以防止或显着地最小化在纤维形成期间形成的嵌段中的残余不饱和度的热交联。 另外,如果例如顺序紊乱转变(ODT)温度低于约280℃,则组合物可被描述为可加工的,而不需要任何添加剂。
