Abstract
Provided is a method of preparing a superabsorbent polymer. More specifically, provided is a method of preparing a superabsorbent polymer capable of exhibiting improved initial absorbency and a rapid absorption rate by polymerizing monomers having acidic groups, of which part is neutralized with a basic material including potassium hydroxide, in the presence of an encapsulated foaming agent.
