Abstract
New compounds which are 4,4'-bis(trihaloacetyl) derivatives of aromatic compounds have been prepared by reacting an aromatic compound with a haloacetyl halide in the presence of a Friedel-Crafts catalyst, e.g. AlCl.sub.3, in a suitable solvent. The compounds are useful in preparing polycarbonates, polyesters, polyamides, polyketones and polyurethanes.
