Title:
NONWOVEN WEB MATERIAL CONTAINING CROSSLINKED ELASTIC COMPONENT FORMED FROM A PENTABLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2009/050608
Kind Code:
A3
Abstract:
A nonwoven web material that includes an elastic component or material (e.g., nonwoven web, nonwoven web laminated to an elastic material, etc.) is provided. The elastic component contains a crosslinked network formed from a pentablock copolymer containing at least two monoalkenyl aromatic midblocks positioned between conjugated diene endblocks, such as butadiene-styrene- butadiene-styrene-butadiene ('BSBSB') or isoprene-styrene-isoprene-styrene- isoprene ('ISISI'). Prior to crosslinking, the pentablock 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.
