Embodiment 1
[0028] 1) Under anaerobic conditions, dissolve 0.1 part of cyclodextrin in 5 parts of DMF according to parts by weight, and add 0.2 part of BIBB (2-bromoisobutyryl bromide) under ice bath conditions, and the temperature of the reaction solution is 0 ℃, then add 0.4 parts of triethylamine, and react at 0-50℃ for 24 hours. After the reaction, the product is precipitated by adding ether until the shape becomes solid, washed with acetone, and placed in a vacuum drying oven to remove ether and acetone. The resulting product is the macroinitiator CD-Br.
[0029] 2) 0-50°C, under anaerobic conditions, first dissolve 0.2 parts of CD-Br in 5 parts of DMF, then add 3 parts of GMA (glycidyl methacrylate) as a monomer, and then add 0.082 parts of ligand N, N,N,N,N-Pentamethyldiethylenetriamine, finally add 0.033 parts of CuBr initiator, polymerize for 1 hour, expose to the air after the reaction, deactivate the initiator system and terminate the polymerization, then add Methanol was prec...
Embodiment 2
[0036] 1) Under anaerobic conditions, dissolve 0.2 parts of cyclodextrin in 10 parts of DMF according to parts by weight, and add 0.6 parts of BIBB under ice bath conditions. At this time, the temperature of the reaction solution is controlled at 0°C, and then add 0.6 parts of triethylamine Amine, react at 0-50°C for 24 hours. After the reaction, the product is precipitated by adding ether until the shape becomes solid, washed with acetone, and put in a vacuum drying oven to remove ether and acetone. The obtained product is a macromolecular initiator CD- Br.
[0037] 2) 0-50°C, under anaerobic conditions, first dissolve 0.5 parts of CD-Br in 10 parts of DMF, then add 6 parts of GMA as a monomer, and then add 0.15 parts of ligand 2,2-bipyridine (BPY), Finally add 0.1 part of CuBr initiator, polymerize for 8 hours, expose to the air after the reaction, deactivate the initiator system and terminate the polymerization, then add methanol to precipitate until the shape becomes solid...
