[0025] Raw materials: isobutyl alcohol polyoxyethylene (65) ether; acrylic acid; solvent: isobutanol; benzene;
[0026] Initiator: benzoyl peroxide; chain transfer agent: mercaptopropionic acid; octyl mercaptan;
[0027] Neutralizing reagent: sodium hydroxide;
[0028] Step 1: Add 120 parts of isobutanol, 120 parts of benzene, and 226 parts of isobutenol polyoxyethylene (65) ether to a flask equipped with a stirring and heating device, raise the temperature to 70°C, and add 1 part of benzoyl peroxide.
[0029] Dissolve 20 parts of acrylic acid in 22 parts of isobutanol and mix to make material A; dissolve 0.3 parts of mercaptopropionic acid and 0.2 parts of octyl mercaptan in 45 parts of isobutanol to make material B. Add material A and material B dropwise to the above-mentioned flask at the same time, control material A to drop in 3 hours, and material B to drop in 3.5 hours. After the dropwise addition was completed, the material was matured for 1 hour.
[0030] Step 2: A...
