| titleOfInvention | Preparation method for dendritic polyfunctional group RAFT (Reversible Addition-Fragmentation Chain Transfer) reagent |
| abstract | The invention relates to a preparation method for a dendritic polyfunctional group reversible addition-fragmentation chain transfer (RAFT) reagent. The preparation method comprises the following steps of: undergoing an amidization reaction on trihydroxymethyl aminomethane and dendritic polyamide-amine of a terminated ester group to synthesize terminal hydroxyl group dendritic polyamide-amine; and under an alkaline condition, undergoing a reaction on carbon disulfide and the terminal ester group dendritic polyamide-amine to generate dendritic polyamide-amine sodium xanthate, and reacting with 2-halogenated carboxylic ester to obtain the xanthate-end-capped dendritic polyfunctional group RAFT reagent. The preparation method is easy and convenient; a product is easy to separate and has high yield; and the synthesized dendritic polyfunctional group RAFT reagent can be taken as a polyfunctional chain transfer reagent for adjusting and controlling RAFT of a vinyl monomer to synthesize a tree kernel star polymer, and the structure, molecular weight and distribution of the tree kernel star polymer can be controlled. |
