Development of Multifunctional Difuranic C11 Building Blocks and their Application in the synthesis of Novel Polyesters and Polyurethanes
Research seminar abstract
Polymeric materials are an essential and ubiquitous part of modern life. Currently, the primary source of building blocks for these increasingly important commodities are supplied by the petroleum industry. The eminent depletion of petroleum feed stocks has led to the need to develop alternative sources of monomers suitable to meet the ever-increasing need for polymeric materials. The most promising source for new polymerizable monomers is the developing biorefining industry. Of the several exciting platform chemicals that have emerged from this new source, 5-hydroxymethylfuraldehyde and furanaldehyde have arisen as particularly interesting because the resulting materials show improved barrier properties when compared to similar polymers currently used. Additionally, the ability of furans to undergo dynamic covalent bonding through the thermally controllable Diels-Alder reaction allows these materials to have interesting properties such as reversible cross linking. This work highlights the development of the previously missing two C11 difuranic multifunctional polymeric building blocks. The presence of the convenient diol moiety opens the door for a series of novel polyesters and polyurethanes with amorphous glassy morphology do to the two types of furan pendant groups. The electron rich α-hydroxyl furan, and the electron deficient α-carbonyl furan.
