Patent

CA 2678406

Thiourethane prepolymer compositions, thiourethane polymer compositions, methods of making the compositions, and methods of using the thiourethane polymer compositions are provided. The thiourethane polymer composition can be produced by contacting a thiol ester composition and an isocyanate composition to produce a prepolymer composition and then curing the prepolymer composition to produce the thiourethane polymer composition. The prepolymer composition can also include a property modifying agent. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.

L'invention concerne des compositions de prépolymère de thiouréthane, des compositions de polymère de thiouréthane, des procédés de fabrication des compositions et des procédés d'utilisation des compositions de polymère de thiouréthane. La composition de polymère de thiouréthane peut être produite en mettant en contact une composition d'ester de thiol et une composition d'isocyanate pour produire une composition de prépolymère puis en durcissant la composition de prépolymère pour produire la composition de polymère de thiouréthane. La composition de prépolymère peut également comprendre un agent de modification de propriété. Dans certains modes de réalisation, les compositions d'ester de thiol comprennent des esters de thiol, des esters d'hydroxy thiol et des esters de thiol réticulés.
