Abstract: A blended polymer comprising, an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 0.05 to about 20 forms a melt blown nonwoven fabric having essentially no defects with long fiber lengths having uniform diameters. The nonwoven fabrics when used as a filter may have greater than 95% efficiency at a pressure drop of less than 2 mm Hg even after being exposed to high temperatures (~70°C) for an hour or more.
