Bis-ethynyl heterocyclic compositions and method of synthesis
-
, (2008/06/13)
Bis-ethynyl quinoxaline compositions are prepared by the condensation reaction of an aromatic diglyoxyl or dibenzil with an ethynyl-substituted aromatic ortho-diamine. The compositions are useful as polymerizable plasticizers for heterocyclic thermoplastic resins in the fabrication of composites. Polymerizable plasticizers are materials that remain fluid and act as a plasticizer during early stages of fabrication and then polymerize to a rigid resin.

As new compositions of matter, ethynyl-substituted aromatic ortho-diamines. The compounds are useful as endcapping agents for thermally stable heterocyclic oligomeric compositions.
Addition curable phenyl-quinoxaline compositions and their synthesis
-
, (2008/06/13)
An aromatic bis(o-diamine) is reacted with an aromatic bisbenzil to provide a benzil end-capped quinoxaline oligomer which is then reacted with 4-(3-ethynylphenoxy)orthophenylene diamine to give an ethynyl terminated polyquinoxaline. Because the polyquino
