POLYOLEFIN-CONTAINING EXTRUDABLE COMPOSITIONS AND METHODS FOR THEIR FORMATION INTO ELASTOMERIC PRODUCTS

Extrudable elastomeric compositions are 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-but...

More Information
Summary:Extrudable elastomeric compositions are 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 about 90 per cent, 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 and elastomeric films and processes for forming them are disclosed.
