Abstract
The present disclosure relates to a preparation method for an acrylic acid-based polymer. According to the preparation method for an acrylic acid-based polymer of the present disclosure, unreacted monomers may be reduced and a high quality acrylic acid-based polymer can be prepared. In addition, it is not necessary to increase the time or the temperature in the polymerization step or the aging step, thereby maintaining the high productivity.
