Abstract: A method for synthesizing functionalized bio-based crosslinkers including forming a first mixture by mixing a bio-based carboxylic acid with an alkaline solution and forming a second mixture containing a functionalized bio-based crosslinker by reacting the bio-based carboxylic acid with a modifier. The modifier includes at least one of an epoxide group and an acrylate group. Reacting the bio-based carboxylic acid with the modifier includes forming a reaction mixture by mixing the first mixture with the modifier and exposing the reaction mixture to at least one of heating, ultrasound radiation, and microwave radiation.

Abstract: A method for producing a cross-linked superabsorbent polymer for recycling superabsorbent polymers may be introduced. The method may include obtaining a solution by mixing a cross-linking agent, an initiator, water, acetone, and a functionalized oligomer. The method may further include obtaining a molded superabsorbent polymer by molding the superabsorbent polymer in a die. The superabsorbent polymer may include a polymer with a water absorbing capacity of more than 100 g/g. the method may further include impregnating the molded superabsorbent polymer with the solution by adding the solution to the molded superabsorbent polymer.

Abstract: A method for surface treatment of acrylate-based superabsorbents may include preparing a treatment solution including water, an organic solvent, and a silane compound; applying the treatment solution to a plurality of acrylate-based superabsorbents to form a mixture; and fabricating modified acrylate-based superabsorbents by subjecting the mixture to heating or microwave irradiation.
