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 a bio-based carboxylic acid with an alkaline solution, the bio-based carboxylic acid comprising at least one of citric acid, itaconic acid, tartaric acid, and succinic acid;
- and
- forming a second mixture containing a functionalized bio-based crosslinker by reacting the bio-based carboxylic acid with a modifier with a molar ratio of the modifier to the bio-based carboxylic acid between 2 and 8, the reacting the bio-based carboxylic acid with the modifier comprising:
- forming a reaction mixture by mixing the first mixture with the modifier, the modifier comprising at least one of glycidyl methacrylate (GMA) and epichlorohydrin (ECH);
- and
- exposing the reaction mixture to at least one of heating, ultrasound radiation, and microwave radiation.
