Super absorbent polymer and preparation method thereof

A preparation method of a super absorbent polymer, comprising:

• preparing a monomer composition by mixing an acrylic acid-based monomer containing an acidic group, a polymerizable antimicrobial monomer represented by the following Chemical Formula 1, a basic material, an internal cross-linking agent, and a polymerization initiator;
• forming a hydrogel polymer by performing thermal polymerization or photopolymerization on the monomer composition;
• and
• forming a super absorbent polymer containing a polymer by drying, pulverizing and classifying the hydrogel polymer,
• wherein the polymerizable antimicrobial monomer is used in an amount of 0.2 to 20 parts by weight based on 100 parts by weight of the acrylic acid-based monomer:
• in the Chemical Formula 1,
• R1 to R3 are each independently hydrogen or methyl, and
• A is a substituted or unsubstituted C6 to C60 aromatic ring.
