    摘要: A compound having: one or more of the below repeat units, one or more terminating Ar—NH— groups bound to carbon radicals, and one or more terminating —H groups bound to nitrogen radicals. Each R is an organic group and each Ar is an aromatic group. The compound is not a thermoset. A method of: mixing an aromatic amine having the formula Ar—NH2 with a phthalonitrile compound, heating the mixture to form the compound described above, and cooling the mixture before the onset of gelation.

    摘要: Disclosed are an oligomer and a phthalonitrile monomer having the formulas: M is a metal or H. The value n is an integer greater than or equal to 1 for the oligomer and greater than or equal to 0 for the phthalonitrile monomer. Ar1 and Ar2 are independently selected aromatic- or heterocyclic-containing groups. Ar1, Ar2, or both are heteroaromatic or heterocyclic groups containing a nitrogen, sulfur, or oxygen heteroatom. Also disclosed are thermosets and pyrolyzed materials made from the phthalonitrile monomer.
