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. |
