Diels-Alder chemistry is utilized for a myriad of commercial applications during polymer synthesis, ranging from self-healing materials to heat responsive materials to emulsion coatings. In particular, the ability to regulate and control the amount and type of functional group linkages is key component for polymer applications. A common strategy that is employed is the use of phenolic maleimide as a dienophile during Diels-Alder synthesis to control the linkages on a polymer, which determines its properties and functionality. This summer was the beginning of a project to prepare a commercial scale, water-based emulsion floor coating/polish. The first step in this project was to synthesize large amounts of Phenolic Maleimide, which is an important reagent in several Diels-Alder reactions. Over the summer, we produced more than 300g of Phenolic Maleimide over eight batches affirming that it can consistently be synthesized on a large scale and successfully creating a working stockpile that will continue to be added upon.
