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.
