Notes:
The use of 1,3-di(5-[2,2,1]-bicyclohexyl-2,3-dicarboxylic anhydride)-1,1,3,3-tetramethyldisiloxane, 1, as a curing agent in the presence of typical epoxy resins with Lewis bases as catalysts produces thermosets with HDTs of 320°C. The solubility of 1 in the epoxy resin allows for the preparation of a one-component formulation. A latent catalyst was developed which employs amine complexes of cobalt bis(2,4-pentanedionate). These formulations exhibit long term storage at ambient conditions, yet cure rapidly at 180-200°C.
