Abstract
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.
