Abstract
Polythiourethane polymer compositions, methods of making the polythiourethane polymer compositions, and methods of using the polythiourethane polymer compositions are provided. The polythiourethane can be produced by contacting a thiol ester composition and an isocyanate to produce a mixture and then heating the mixture to produce the polythiourethane polymer. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.
