04663220 is referenced by 787 patents and cites 28 patents.

The disclosure is generally directed to an extrudable elastomeric composition formed by blending from at least 10 percent, by weight, of an A-B-A' block copolymer where "A" and "A'" are each a thermoplastic endblock which includes a styrenic moiety and where "B" is an elastomeric poly(ethylene-butylene) midblock with up to at least about 90 percent, by weight, of at least one polyolefin which, when blended with the A-B-A' block copolymer and subjected to an effective combination of elevated temperature and elevated pressure conditions, is adapted to be extruded in blended form, with the A-B-A' block copolymer. Fibrous nonwoven elastomeric webs may be formed from the extrudable composition and processes for forming the fibrous nonwoven elastomeric webs are also disclosed.
