Abstract
Official abstract text for this publication.
Bis(sulfonyl)alkanol-containing polythioethers, compositions containing bis(sulfonyl)alkanol-containing polythioethers, methods of synthesizing bis(sulfonyl)alkanol-containing polythioethers and the use of bis(sulfonyl)alkanol-containing polythioethers in aerospace sealant applications are disclosed. The bis(sulfonyl)alkanol-containing polythioethers have bis(sulfonyl)alkanol groups incorporated into the backbone of the polythioether. Cured sealant compositions comprising the bis(sulfonyl)alkanol-containing polythioethers exhibit enhanced properties suitable for aerospace sealant applications.
First claim
Opening claim text (preview).
What is claimed is: 1. A bis(sulfonyl)alkanol-containing polythioether comprising a moiety of Formula (10): —S(O) 2 —R 10 —CH(—OH)—R 10 —S(O) 2 — (10) wherein each R 10 is independently selected from a C 1-3 alkanediyl and substituted C 1-3 alkanediyl, wherein one or more substituent groups is —OH. 2. The polythioether of claim 1 , comprising a moiety of Formula (1): -A-R 9 —S(O) 2 —R 10 —CH(—OH)—R 10 —S(O) 2 —R 9 -A- (1) wherei…
