Embodiment 1
[0030] (1) Preparation of cadmium acrylate:
[0031] Melt acrylic acid at room temperature, weigh a certain amount of cadmium hydroxide, and grind it into a fine powder with a mortar. Measured 12ml of acrylic acid and 20ml of deionized water were added to the flask, and 12g of the above-mentioned finely ground cadmium hydroxide was added, and reacted at room temperature for 12 hours. The product is washed with acetone, filtered by suction and put into a vacuum drying oven to dry at room temperature to obtain a white powder monomer cadmium acrylate, which is sealed and stored at low temperature.
[0032] (2) Preparation of polystyrene macroinitiator:
[0033] After evacuating the dry Kelvin bottle for 3 times, add 0.1248g of cuprous bromide and 0.4077g of 2,2'-bipyridine in sequence, pat it to make it complex, seal it with a sealing tape, and then vacuumize and fill it. Nitrogen gas 3 times, inject 128 μl initiator α-bromoisobutyrate ethyl ester and 10ml styrene sequentially ...
Embodiment 2
[0039] In this embodiment, the preparation method of cadmium acrylate and polystyrene macromolecular initiator is the same as that shown in Example 1.
[0040]Fill the dry Kelvin flask with nitrogen after removing the air, repeat the operation three times, add 0.0166g of cuprous bromide and 0.0478g of 2,2'-bipyridine, tap it to make it complex, form a black powder, then add 1g of polystyrene macromolecular initiator and 0.057g of cadmium acrylate, after vacuuming and blowing nitrogen for 3 times, inject 1.2ml of butyl methacrylate and 5ml of N,N-dimethylformamide sequentially with a syringe, seal and put After reacting in a constant temperature oil bath at 90 degrees Celsius for 12 hours, the product was precipitated with methanol, filtered with suction, and dried in a vacuum oven at 40 degrees Celsius for 24 hours to obtain a cadmium acrylate copolymer.
[0041] Use the GPC test method to measure the degree of polymerization: the test means is as shown in Example 1, and the d...
Embodiment 3
[0043] In this embodiment, the preparation method of cadmium acrylate and polystyrene macromolecular initiator is the same as that shown in embodiment 1.
[0044] Fill the dry Kelvin bottle with nitrogen after removing the air, repeat the operation three times, add 0.0186g of cuprous bromide and 0.0568g of 2,2'-bipyridine, tap it to make it complex, form a black powder, then add 1g of polystyrene macromolecular initiator and 0.095g of cadmium acrylate, after vacuuming and blowing nitrogen for 3 times, inject 1.2ml of butyl methacrylate and 5ml of N,N-dimethylformamide sequentially with a syringe, seal and put After reacting in a constant temperature oil bath at 100 degrees Celsius for 12 hours, the product was precipitated with methanol, filtered with suction, and dried in a vacuum oven at 40 degrees Celsius for 24 hours to obtain a cadmium acrylate copolymer.
[0045] Use the GPC test method to measure the degree of polymerization: the test means is as shown in Example 1, and...
