Polyphthalocyanine

摘要

The present invention pertains generally to high-temperature resins and in particular to cyano-addition resins from oxyarylbisorthodinitriles. Certain bisorthodinitriles polymerize to form strong, high-temperature thermosetting resins. The structure of these resins is not completely known. For the following reasons, the principal mechanism of formation is theorized to be phthalocyanine nucleation. As the bisorthodinitriles polymerize, the color becomes progressively darker green in the manner similar to phthalocyanines. The polymerization is difficult to initiate and promote which indicates the formation of a large and complex nucleus such as the phthalocyanine nucleus by a large end group such as the phthalonitrile group. The resins have properties that make them exceptionally suitable for structural resins. They have a structural strength comparable to that of epoxy and polyimide resins and have many advantages over these resins.
