Title (EN) REACTIONS ENABLED BY THERMORESPONSIVE AND PHOTORESPONSIVE GELS
(FR) RÉACTIONS ACTIVÉES PAR DES GELS THERMOSENSIBLES ET PHOTOSENSIBLES
Abstract:
(EN) Disclosed are methods, compositions, kits, and reagents to prepare compounds (e.g. polymers and small molecules) via radical reactions by utilizing thermoresponsive and photoresponsive gels. This invention discloses the preparation of polymers via controlled radical polymerizations from an iniferter or initiator, one or more reactant monomer, and a thermoresponsive and photoresponsive gel. Embodiments of the invention show that the polymerization is reversibly activated and/or deactivated by controlling one or more of the following external control stimuli: temperature, light, and catalyst presence. This invention also relates the preparation of Gel-PTH, a heterogeneous thermoresponsive and photoresponsive gel.
(FR) L'invention concerne des procédés, des compositions, des trousses, des réactifs pour préparer des composés (par exemple des polymères et de petites molécules) par des réactions radicalaires grâce à l'utilisation de gels thermosensibles et photosensibles. L'invention porte sur la préparation de polymères par des polymérisations radicalaires contrôlées à partir d'un iniferter ou d'un amorceur, d'un ou plusieurs monomères réactifs et d'un gel thermosensible et photosensible. Des modes de réalisation de l'invention montrent que la polymérisation est activée et/ou désactivée d'une manière réversible par régulation d'un ou plusieurs des stimuli régulateurs externes suivants : température, lumière, et présence d'un catalyseur. La présente invention concerne également la préparation de gel-PTH, un gel thermosensible et photosensible hétérogène.
