Definitions
- R is an alkyl group having 2 to 5 carbon atoms including an unsaturated bond
- the superabsorbent polymer composition contains a carboxylic acid having a structure of A-(EO) m -COOH and a compound having a structure of HO-B 2 -C. may include more.
- the superabsorbent polymer composition of one embodiment includes polyethylene glycol, polypropylene glycol, poly(ethylene glycol)-poly(propylene glycol) copolymer, polyoxyethylene lauryl ether carboxylic acid, sodium polyoxyethylene lauryl ether carboxyl It may not contain hydrophilic additives such as lactate, lauryl sulfate, sodium lauryl sulfate, and the like. Since these additives do not have the (B 1 -B 2 ) moiety of Formula 1 in the molecule, they cannot be sufficiently adsorbed to the surface of the cross-linked polymer, so that aggregation between the super absorbent polymer particles is not effectively suppressed.
- hydrophilic additives such as lactate, lauryl sulfate, sodium lauryl sulfate, and the like. Since these additives do not have the (B 1 -B 2 ) moiety of Formula 1 in the molecule, they cannot be sufficiently adsorbed to the surface of the cross-linked polymer,
- the superabsorbent polymer composition may be prepared by crosslinking and polymerizing a water-soluble ethylenically unsaturated monomer having an acidic group at least partially neutralized in the presence of an internal crosslinking agent and a polymerization initiator to form a hydrogel polymer; mixing the hydrogel polymer with the carboxylic acid-based additive and pulverizing the hydrogel polymer to prepare a pulverized product containing the water-containing superabsorbent polymer particles and the additive; and drying the pulverized product to prepare a superabsorbent polymer composition including the superabsorbent polymer particles and the additive.
- the step may include preparing a monomer composition by mixing the water-soluble ethylenically unsaturated monomer, an internal crosslinking agent and a polymerization initiator, and thermally or photopolymerizing the monomer composition to form a hydrogel polymer.
- a monomer composition by mixing the water-soluble ethylenically unsaturated monomer, an internal crosslinking agent and a polymerization initiator, and thermally or photopolymerizing the monomer composition to form a hydrogel polymer.
- the description of the water-soluble ethylenically unsaturated monomer and the internal crosslinking agent refer to the above bar.
- the monomer composition may further include additives such as a thickener, a plasticizer, a storage stabilizer, and an antioxidant, if necessary.
- additives such as a thickener, a plasticizer, a storage stabilizer, and an antioxidant, if necessary.
- Example 1 instead of laureth-3-adipate represented by Formula 1-1, laureth-3-suberate represented by the following Formula X-5 (laureth-3-suberate, Afcona) A superabsorbent polymer composition was prepared in the same manner as in Example 1, except that) was used.
