preparation example 1
[0042] (1) The aqueous solution of monomeric acrylic acid and acrylamide is fed in a certain molar ratio, heated to reflux at 90°C under an inert atmosphere, and 0.3wt% of the total monomer mass is added as an initiator potassium persulfate-sodium bicarbonate (1:1, w / w) Initiate the polymerization reaction for 0.5-1h;
[0043] (2) Add 3,3'-diallyl diphenol (the molar ratio of acrylic acid, acrylamide, 3,3'-diallyl diphenol is 5:1:0.1), continue at 80 React at -90°C for 6 hours, dehydrate, cool, wash, and dry to obtain a water-absorbent resin, hereinafter referred to as water-absorbent resin 1. The weight-average molecular weight of the water-absorbent resin obtained through GPC test was 957200 g / mol, and PDI=1.92.
preparation example 2
[0045] Other conditions and steps are the same as in Preparation Example 1, except that the molar ratio of acrylic acid, acrylamide, and 3,3'-diallyl biphenol is 5:1:0.2. The weight-average molecular weight of the water-absorbing resin obtained through GPC test was 1268400 g / mol, and PDI=2.13. Hereinafter, it is referred to as water-absorbent resin 2 .
preparation example 3
[0047] Other conditions and steps are the same as in Preparation Example 1, except that the molar ratio of acrylic acid, acrylamide, and 3,3'-diallyl biphenol is 5:1:0.3. The weight-average molecular weight of the water-absorbent resin obtained through GPC test was 1457100 g / mol, and PDI=2.28. Hereinafter, it is referred to as water-absorbent resin 3 .
