Abstract
Polysulfones and methods for forming polysulfones are disclosed herein. The polysulfones are prepared from thiols and hexahydrotriazines. The thiols may be, for example, dithiols, trithiols, monothiols, or mixtures thereof. The thiols and hexahydrotriazines may be polymerized to form a polythioether. The polythioether may thereafter be oxidized to form a polysulfone. The polysulfones are prepared from an efficient and simple synthetic method, and the properties of the prepared polysulfones can be readily tuned. The prepared polysulfones may have improved thermal properties, improved mechanical properties, and enhanced functionality.
