ABSTRACT:
The invention is directed to elastomeric meltblown webs having desirable strength and stretch/recovery properties which can be produced at relatively high throughputs and/or relatively low die pressures. The meltblown webs of the invention comprise a blend of (i) a fully hydrogenated diblock or triblock thermoplastic elastomer copolymer or mixtures thereof based on polystyrene and poly(ethylene-butylene) blocks; and (ii) from about 5% by weight up to about 50% by weight of a copolymer of ethylene and acrylic acid or ethylene and a lower alkyl ester of acrylic acid in which the ethylene content ranges from about 5% by weight up to about 50% by weight.
