摘要：
A nonwoven web material that contains an elastic component is provided. The elastic component contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene ("B-S-B") thblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic component that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.
摘要（中）：
提供含有弹性组分的非织造纤维网材料。 弹性组分含有由位于共轭二烯末端嵌段（例如丁二烯 - 苯乙烯 - 丁二烯（“B-S-B”）三嵌段共聚物）之间的具有单链烯基芳族中间嵌段的线型嵌段共聚物形成的交联网络。 在交联之前，这种线性嵌段共聚物具有相对较低的粘度，因此可以容易地形成前体弹性组分，其随后交联以获得期望的弹性和机械性能。 通常通过形成连接在一起以在共轭二烯末端嵌段上形成多个碳 - 碳共价键的自由基（不成对电子）形成交联。
