sulfone-containing polythioether, thiol-terminated sulfone-containing polythioether, thiol-terminated sulfone-containing polythioether prepolymer, method for preparing a polythioether adduct, method for preparing a polythioether adduct and composition

摘要

"sulfone-containing polythioether, thiol-terminated sulfone-polythioether, thiol-terminated sulfone-polythioether prepolymer, method for preparing a polythioether adduct, method for preparing a polythioether adduct and composition" disclosed are sulfone-containing polythioethers, compositions containing sulfone containing polyethers, methods for synthesizing sulfone containing polyethers and the use of sulfone containing polyethers in aerospace sealant applications. sulfone containing polyethers have sulfone groups incorporated into the main chain of the polyether. Cured seal compositions comprising the sulfone containing polyether ethers exhibit improved thermal resistance. 1/1
