Phthalonitrile Monomers Containing Imide and/or Phenoxy Linkages, and Polymers Thereof.
Abstract
This patent application discloses a highly aromatic oligomeric imide-containing phthalonitriles that are prepared by reacting an aromatic dianhydride with an aromatic or aliphatic diamine and endcapping the resulting reaction product with 4-aminophthalonitrile. The prepolymers are highly stable to storage. When heated above their melting or softening points, they polymerize to a thermosetting polymeric material useful as an advanced matrix material. In the case where the oligomeric monomers are produced by reacting dianhydrides with aromatic diamines, they polymerize to form high-temperature adhesives. Keywords: Patent applications, Phthalonitrile monomers, Imides, Phenoxy linkages, Polymers, Advanced matrix material. (JG)
