Effects of Air/Nitrogen Cure on An Acetylene Terminated Quinoxaline Thermoset System

Abstract

TICA temperature scan results of AT systems indicated the presence of two different reactions with different activation energies. Two additional effects are delineated when cure is carried out in the presence of air. Curing at low temperature in the presence of air will lower the final Tg, but at high temperature will have the opposing effect. The two reactions that can occur under nitrogen are affected differently by air-curing. It appears that one is prohibited by the lower temperature curing in air while the other is not. The issues raised from the findings of this work were discussed.
