Abstract

Compositions useful in aerospace sealant applications comprise sulfur-containing polymers such as polythioethers and polysulfides and are cured using Michael addition reactions. Compositions employing Michael addition curing chemistries include sulfur-containing adducts comprising terminal Michael acceptor groups. In particular, the sulfur-containing adducts include terminal 1-(ethylenesulfonyl)-n-(vinylsulfonyl)alkanol groups.
