COMPOSITION INCLUDING A POLYTHIOL AND A POLYEPOXIDE AND METHODS RELATING TO THE COMPOSITION

A composition including a polythiol having more than one thiol groups, a polyepoxide having more than one epoxide group, a catalytic amount of a second amine, and a photolatent base catalyst. The photolatent base catalyst can photochemically generate a first amine, which may be the same as or differ...

More Information
Summary:A composition including a polythiol having more than one thiol groups, a polyepoxide having more than one epoxide group, a catalytic amount of a second amine, and a photolatent base catalyst. The photolatent base catalyst can photochemically generate a first amine, which may be the same as or different from the second amine. A polymer network preparable from the composition, and a method for making the polymer network are also disclosed. L'invention concerne une composition comprenant un polythiol ayant plus d'un groupe thiol, un polyépoxyde ayant plus d'un groupe époxyde, une quantité catalytique d'une seconde amine, et un catalyseur de base photolatente. Le catalyseur de base photolatente peut générer de manière photochimique une première amine, qui peut être identique à la seconde amine ou différente de celle-ci. L'invention concerne également un réseau polymère pouvant être préparé à partir de la composition, et un procédé de fabrication du réseau polymère.
