ABSTRACT:
The present invention provides a melt processable composition and process for preparing the same from a blend of a normally non-melt processable wholly aromatic polyester and a phosphorus ester. The presence of the specifically defined phosphorus ester in the composition in amounts of up to about 40 percent by weight renders the normally non-melt processable wholly aromatic polyester melt processable.
