Beschreibung
Zusammenfassung:	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. L'invention concerne des procédés de production et d'utilisation de compositions macromoléculaires. Ces procédés consistent à préparer une substance résineuse ; à former un groupe acétyle sur la substance résineuse ; et à oxyder le groupe acétyle par l'intermédiaire d'une réaction en une étape consistant à faire réagir un sulfoxyde et un acide avec le groupe acétyle, pour former un groupe cétoaldéhyde. Les compositions macromoléculaires permettent d'éliminer sensiblement un ou plusieurs constituants d'une solution physiologique, tels que l'urée durant une dialyse.
