Crosslinking of commercially available epoxy Novolac resins by both diaminodiphenyl sulfone (DDS) and bisphenol curing agents were studied. The glass transition temperatures of the networks are influenced by both catalysts and the curing agents. The bisamino cured resin exhibits a higher glass transition temperature than the Bis-S cured system. However, high apparent moduli can be observed by TMA for the Bis-S cured system even above the glass transition temperatures. These initial results provide a basis for future studies of polymer modified matrix resin and coating systems.
