Embodiment 1
[0095] Synthesis of the anionic chlorine-containing amphiphilic polymer P1 with the chlorine-containing macromolecule dispersant D1 solution as the dispersant:
[0096] Add 100g N, N dimethylacetamide (DMAC), 6g of vinylidene chloride, 5g of acrylic acid, 0.1g of initiator benzoyl peroxide (BPO) into the reactor, dissolve and stir at room temperature for 30 minutes under the condition of nitrogen to remove from the system oxygen. Under the condition of reflux, the temperature was raised to the polymerization temperature of 62° C., and the polymerization reaction was carried out. After 5.5 hours of reaction, the heating was stopped, and air was introduced to terminate the reaction. Obtain chlorine-containing macromolecular dispersant D1 solution. Add 2000ml of deionized water, 1.2g of D1 solution, 1g of bis(2-ethylhexyl) peroxydicarbonate (EHP) into the stainless steel reactor, vacuumize and fill with nitrogen for 3 times, then add 1500g of vinylidene chloride , Solubilizer ...
