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.

A method for synthesizing functionalized bio-based crosslinkers, comprising:
- forming a first mixture by mixing itaconic acid with an alkaline solution;
- forming a second mixture containing a functionalized bio-based crosslinker by reacting the itaconic acid with a modifier with a molar ratio of the modifier to the itaconic acid between 2 and 8, the reacting the itaconic acid with the modifier comprising:
- forming a reaction mixture by mixing the first mixture with the modifier, the modifier comprising epichlorohydrin (ECH);
- exposing the reaction mixture to at least one of heating, ultrasound radiation, and microwave radiation;
- and
- crosslinking acrylic acid monomers by mixing the acrylic acid monomers with the functionalized bio-based crosslinker,
- wherein the mixing the acrylic acid monomers with the functionalized bio-based crosslinker comprises mixing the acrylic acid monomers with the functionalized bio-based crosslinker with a ratio the functionalized bio-based crosslinker to the acrylic acid monomers between 2.5 gram/Kg and 10 gram/Kg.
