Abstract: Thiol-terminated polythioether compositions and sealants prepared using the thiol-terminated polythioether compositions that exhibit enhanced retention of elongation following exposure to high temperature are disclosed. The enhanced retention of elongation is realized by incorporating certain phenolic antioxidants into the composition.
