Examples
Embodiment 1
[0041] 1. Add 61.65g of Johnson resin J-671, 8g of triallylamine, and 356.3g of water into the reaction kettle, stir until completely dissolved, and raise the temperature to 80°C to obtain system 1.
[0042] 2. Mix 100g of styrene, 20g of methyl methacrylate, 60g of n-butyl acrylate, 25g of n-butyl methacrylate and 2.05g of methacrylic acid, and add them dropwise to system 1 in 3 hours, while dissolving 0.6 Add 20 g of water in 1 g of ammonium persulfate dropwise to System 1 in 3 hours to obtain System 2.
[0043] 3. Heat system 2 to 90°C, keep it warm for 1.5h, cool down to room temperature, adjust the pH value to about 8, and filter out.
[0044] From figure 1 It can be seen in the T of the solid resin g at around 128°C, while the T of the acrylate copolymer g Around 34°C; figure 2 It can be seen that the average particle size is 45nm, and the resulting emulsion is translucent.
