  • Modified bisimide compositions
    Patent number: 5770681
    Abstract: The solution stability of a modified bisimide resin is enhanced by partially polymerizing a mixture of a bisimide monomer and a reactive triene which contains a conjugated double bond capable of Diels-Alder reaction with the bisimide. Such partial polymerization of a bisimide with a reactive triene such as myrcene provides a modified bisimide having good solubility in an organic solvent.
