Examples
Embodiment 1
[0049] Weigh 0.60 g of octylphenol polyoxyethylene ether, 0.30 g of nonylphenol polyoxyethylene ether, and 0.40 g of sodium dodecylsulfonate, add them to the reaction flask, add 15.0 g of water, stir at room temperature for 20 minutes, and then heat up to At 70°C, add 0.85g of polymerized monomer acrylic acid, 3.50g of acrylamide, 5.20g of styrene and 15.00g of ethyl acrylate, add 0.080g of ammonium persulfate and 28.0g of water. React at 70-80°C for 5h. The styrene content was analyzed by gas chromatography, and when it was less than 1%, the reaction was stopped to obtain a uniform emulsion with blue fluorescence.
Embodiment 2
[0051] Weigh 0.30g of fatty alcohol polyoxyethylene ether, 0.50g of polyoxyethylene oleate, 0.20g of octylphenol polyoxyethylene ether, 0.20g of nonylphenol polyoxyethylene ether, 0.40g of sodium dodecylsulfonate, Add 15.5g of water, stir at room temperature for 20min, then raise the temperature to 70°C, add 1.90g of polymerized monomer acrylic acid, 0.50g of N-methacrylamide, 15.60g of styrene, 5.10g of ethyl acrylate, and 1.50g of acrylonitrile. Ammonium sulfate 0.10g and 23.5g water. React at 70-80°C for 5h. The styrene content was analyzed by gas chromatography, and when it was less than 1%, the reaction was stopped to obtain a uniform emulsion with blue fluorescence.
Embodiment 3
[0053] Weigh 0.20 g of phenylethylphenol polyoxyethylene polyoxypropylene ether, 0.22 g of alkylphenol formaldehyde resin polyoxyethylene ether, and 0.30 g of nonyl polyoxyethylene ether potassium sulfate, add 12.0 g of water, stir at room temperature for 30 minutes, and then heat up To 80°C, weigh 0.70g of acrylic acid, 0.15g of acrylamide, 11.44g of styrene, 11.00g of ethyl acrylate, and 3.50g of acrylonitrile into a reaction flask, add 0.071g of ammonium persulfate and 10.0g of water, and React at 90°C for 3h. The styrene content was analyzed by gas chromatography, and when it was less than 1%, the reaction was stopped to obtain a uniform emulsion with blue fluorescence.
