Embodiment 1
[0095]The chlorine-containing macromolecular dispersant D1 solution is the synthesis of the dispersant-containing chlorine-containing amphiphilic polymer P1:
[0096]100 GN, N dimethyl acetamide (DMAC), chlorine ethylene 6g, 5 g of acrylic acid, initiator gauze (BPO) 0.1 g, nitrogen gas dissolved, stirred solutions in a nitrogen-free condition for 30 minutes. oxygen. The polymerization reaction was warmed to a polymerization temperature of 62 ° C in the case of reflow. The reaction was stopped for 5.5 hours, and the air stopped in the air was passed. The chlorine macromolecular dispersant D1 is obtained. 2000 ml of deionized water, D1 solution was added to the stainless steel reaction kettle, and the trigger peroxide di (2-ethylhexhexidin) ester (EHP) 1 g, and the vacuum and filled nitrogen-filled gas were added 3 times. Extra chloride 1500g The solubilizer is 7.5 g of propyl formate, pre-dispersed at room temperature for 30 minutes. The temperature was raised to 50 ° C polymerization ...
