Abstract
Methods and formulations for distortional thermosets are disclosed that display enhanced composite mechanical performances and robust sorption resistance. The composition includes an epoxy resin of formula (I):and a diamine curing agent. The resultant distortional thermoset compositions possess superior out-life requirements and advantageous reaction kinetics for preparing prepreg compositions and materials.
