ABSTRACT:
Methods of producing macromolecular compositions and using same are provided. The method includes preparing a resin material; forming an acetyl group on the resin material; and oxidizing the acetyl group via a one-step reaction including reacting a sulfoxide and an acid with the acetyl group to form a ketoaldehyde group. The macromolecular compositions are capable of removing an effective amount of one or more constituents from a physiological solution, such as urea during dialysis therapy.
