Abstract
A polymer composition, stretched and unstretched articles and processes to make stretched and unstretched articles from that composition are set forth wherein the composition comprises a blend of a polyamide wherein the amino to carboxyl end group ratio of the polyamide polymer is less than 1.0 when the relative viscosity of the polyamide polymer is less than 2.0, and less than 0.30 when the relative viscosity is in the range of 2.0 to 2.3 and less than 0.20 when the relative viscosity is greater than 2.3, a crystallizable polyester and an interfacial tension reducing agent.
