Abstract : The present invention concerns itself with novel iodine containing polyaromatic amides which are synthesized by effecting a reaction between: (1) an iodine containing diacid chloride; and (2) a suitable aromatic diamine. Polyamides containing a desirable phenylethynyl group can then be synthesized by replacing the iodo groups of the polyaromatic amides with a phenylethynyl group by treating with cuprous phenylacetylide. Accordingly, the primary object of this invention is to provide new processable polyaromatic amides. Another object of this invention is to provide novel polyaromatic amides that exhibit good solubility before curing and improved thermal and chemical resistance after heating. Still another object of this invention is to provide novel polyaromatic amides curable by intramolecular cyclization.
