Embodiment 1
[0018] Embodiment 1: the synthesis of poly(2-vinylpyridine)
[0019] Pour 80ml of hydroxypropylmethylcellulose (0.15g) aqueous solution into the polymerization bottle, add 25.7ml (25g) of 2-vinylpyridine, 0.2g of benzoyl peroxide, turn on the condensed water, start stirring to mix the reaction reagents evenly , and then pass high-purity nitrogen to eliminate the influence of soluble gases in the polymerization process. After 15 minutes, start heating with a constant temperature device, rapidly increase the reaction temperature to above 65°C, and maintain a certain stirring speed for suspension polymerization for a period of time (1-2h). The reaction temperature was increased to 85°C for another period of time (3h). After the product was washed with a large amount of hot water, it was dried naturally and then vacuum-dried at 60°C.
Embodiment 2
[0020] Embodiment 2: Synthesis of 2-vinylpyridine and styrene copolymer
[0021] Pour 80ml of hydroxypropylmethylcellulose (0.15g) aqueous solution into the polymerization bottle, add a mixture of 2-vinylpyridine and styrene at a mixing ratio of 0.2:1 to 0.8:1, 0.2g of benzoyl peroxide, Turn on the condensed water, start stirring to mix the reaction reagents evenly, and then pass high-purity nitrogen gas to eliminate the influence of soluble gases in the polymerization process, start heating with a constant temperature device after 15 minutes, quickly increase the reaction temperature to above 65 °C, and maintain a certain stirring speed Carry out suspension polymerization for a period of time (1-2h), raise the reaction temperature to 85°C and react for a period of time (3h). After the product was washed with a large amount of hot water, it was dried naturally and then vacuum-dried at 60°C.
[0022] The synthetic reaction of 2-vinylpyridine and trifluorostyrene copolymer is t...
Embodiment 3
[0023] Embodiment 3: the synthesis of poly(4-vinylpyridine)
[0024] The synthetic method of poly(4-vinylpyridine) resin is the same as in Example 1.
