Abstract
The synthesis and subsequent polymerization of highly aromatized phthalonile monomers which contain phenoxy linkages having a substantially aromatic spacer moiety between the two terminal phthalonitrile groups is disclosed. The phthalonitriles are synthesized by a nucleophilic displacement of a nitro substituent, which is activated by the ring cyano groups on the aromatic ring, by a phenoxide containing unit. The phthalocyanine polymers have improved toughness, low water absorptivity and higher thermal and oxidative resistance than currently available polymers.
