| titleOfInvention | A kind of water-soluble trithiocarbonate RAFT agent and preparation method and application thereof |
| abstract | The invention provides a water-soluble trithiocarbonate RAFT agent and a preparation method and application thereof. Potassium hydroxide is dissolved in distilled water, and after complete dissolution, thiolactic acid is added and stirred; then carbon disulfide is added to obtain an orange-yellow solution, which is stirred; Potassium hydroxide, chloroform, acetone and phase transfer catalyst were added to the obtained solution, stirred at the same temperature, and concentrated hydrochloric acid was added to carry out acidification reaction; then, the obtained solution was separated and filtered to remove oily matter and insoluble matter, Evaporate crystallization, and after filtration and drying, S-(2-propionic acid)-S'-(2-methylpropionic acid) trithiocarbonate water-soluble trithiocarbonate RAFT agent can be obtained. The water-soluble RAFT agent prepared by the invention introduces a plurality of water-soluble group carboxyl groups (-COOH) to improve the water-solubility of the chain transfer agent, can realize the one-pot method of RAFT aqueous solution polymerization to prepare nano-scale gel dispersion, and simplifies the regulation and displacement. The preparation process of the agent solves the problem of large particle size of the general adjusting agent, and effectively avoids the problem of environmental pollution caused by the use of organic solvents. |
