Embodiment 1
[0030] First, 100 milliliters of deionized water, 20 g of sodium lauryl sulfate with a weight content of 10%, and 16 g of a fatty alcohol polyoxyethylene ether solution with a weight content of 40% were added to the reaction kettle, and stirred and emulsified for 30 minutes; followed by adding 25 grams of styrene 10 grams of methyl methacrylate heated up to 40°C and continued to stir and emulsify for 30 minutes;
[0031] Then add 3g of ammonium persulfate solution with a weight content of 10%, and 3g of a sodium bisulfite solution with a weight content of 10%, and heat up to 70±2°C for 3 hours; then cool down to 20±5°C, and then add isoprene 70 grams, 30 grams of butadiene, and 5 grams of methacrylic acid. After 2 hours of reaction, the temperature was raised to 40±3°C, and the reaction was continued for 2 hours; To discharge at room temperature, the product is obtained, and the product is tested according to the SH / T 1593-1609-1994 standard, and the results are as follows:
...
