Abstract
Disclosed are molded articles comprising a melt blown assembly of thermally bonded, longitudinally oriented fibers, said fibers comprising a continuous polymer matrix having dispersed therein microbeads of a material which is incompatible with said polymer matrix which are at least partially bordered by void space, said microbeads being present in an amount of about 5-50% by weight based on the weight of polymer matrix, said void space occupying about 2-60% by volume of said fibers.
