MICHAEL ADDITION CURING CHEMISTRIES FOR SULFUR-CONTAINING POLYMER COMPOSITIONS EMPLOYING BIS(SULFONYL)ALKANOLS

摘要

Michael addition curing chemistries in compositions comprising sulfur-containing polymers such as polythioethers and polysulfides are useful in aerospace sealant applications. 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.
