Abstract
Described herein are polyesters and polyamides which contain repeat units derived from novel dicarboxylic acids comprising arylene groups having ortho ethers substituted thereon. Also disclosed are novel compounds from which these polymers can be made. The polymers are especially useful for molding resins and coatings.
Claims16
A polymer comprising the repeat unit ##STR28## wherein Ar.sup.1 is arylene or alkyl- or halo-substituted arylene and in which the ether oxygen atoms are substituted on Ar.sup.1 in ortho positions, said polymer further comprising at least one other repeat unit such that said polymer is a polyester, a fusible polyamide or a poly(amide-ester).
