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.

L~invention concerne des compositions de polymère époxy durci au mercaptan et des procédés de fabrication desdites compositions de polymère époxy durci au mercaptan, et des procédés d~utilisation desdites compositions de polymère époxy durci au mercaptan. On peut produire des compositions de polymère époxy durci au mercaptan en mettant en contact une composition d~ester de thiol et une composition époxyde afin de produire un mélange, puis en chauffant ledit mélange de manière à produire le polymère époxy durci au mercaptan. Dans certains modes de réalisation, les compositions d~esters de thiol comprennent des esters de thiol, des esters de thiol hydroxy et des esters de thiol réticuléS. L~invention concerne également des compositions de polymère adhésif, des procédés de fabrication desdites compositions de polymère adhésif et des procédés d~utilisation desdites compositions de polymère adhésif. On peut produire la composition de polymère adhésif en mettant en contact une composition d~ester de thiol et une composition époxyde afin de produire un mélange puis en chauffant ledit mélange de manière à produire la composition de polymère adhésif.
