Crosslinked elastic material formed from a branched block copolymer

An elastic material for use in an absorbent article is provided. The elastic material contains a crosslinked network formed from a branched block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, the branched block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic material (e.g., film, strands, web, etc.) 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.
