ABSTRACT:
Bis(haloacylaromatic) compounds have been made by a new process in which monohaloacylated aromatic compounds have been reacted by a coupling reaction. These bis(haloacylaromatic) compounds can be employed as monomers in the preparation of polyesters and polyamides which have easy processability. The monohaloacylated compound is coupled by reacting two moles of the monomer with a carbon or sulfur compound containing at least two halogen atoms in the presence of a Friedel-Crafts catalyst.
