摘要：
A nonwoven web material that contains an elastic component is provided. The elasticcomponent contains a crosslinked network formed from a linear block copolymerhaving a monoalkenyl aromatic midblock positioned between conjugated dieneendblocks (e.g., butadiene-styrene-butadiene ("B-S-B") thblockcopolymer). Prior to crosslinking, such linear block copolymers have a relativelylow viscosity and thus may be readily formed into a precursor elastic componentthat is subsequently crosslinked to achieve the desired elastic and mechanicalproperties. Crosslinking is typically achieved through the formation of freeradicals (unpaired electrons) that link together to form a plurality of carbon-carboncovalent bonds at the conjugated diene endblocks.
