Abstract
Mercaptan-hardened epoxy polymer compositions, methods of making the mercaptan-hardened epoxy polymer compositions, and methods of using the mercaptan-hardened epoxy polymer compositions are provided. The mercaptan-hardened epoxy polymer can be produced by contacting a thiol ester composition and an epoxide composition to produce a mixture and then heating the mixture to produce the mercaptan-hardened epoxy polymer. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and crosslinked thiol esters. Adhesive polymer compositions, methods of making the adhesive polymer compositions, and methods of using the adhesive polymer compositions are provided. The adhesive polymer composition can be produced by contacting a thiol ester composition and an epoxide composition to produce a mixture and then heating the mixture to produce the adhesive polymer composition.
