Abstract

The molding properties of molding compounds based on wholly aromatic polyesters are improved by the addition to such wholly aromatic polyester compositions of a minor amount of an aromatic polyester which is a combination of the following units: ##STR1## Where; p=0 to 0.9, q=0.1 to 1.00, r=1 to 7, S=0.3 to 1.00, t=0 to 0.7. A preferred formulation consists of a polyester where the units are: p=0, q=1.0, r=1 to 5 and S=1.0.
