Abstract
Ugi 4-component reaction (Ugi 4CR) is an efficient tool which benefits from high atom efficiency, compatibility with green solvents such as methanol, simple purification, and a water side-product. By using two bifunctional starting materials for Ugi 4CR, N-substituted polyamides can be prepared via a step-growth process. As polyamides play important roles in applications including films, and adhesives, the preparation of N-substituted functional polyamides from largely sustainable monomers is investigated. Herein, the combination of renewable diamine, diacid, and aldehydes with commercially available isocyanides yield polyamides with tuneable side chain functionalities and ≈80% biomass content. Relatively high yields (up to 96%) are recorded for polymers of moderate molecular weights (Mw up to 8100 g mol−1). The prepared polyamides possess backbones which exhibit excellent thermal stability (Tdeg = 440 ± 10 °C), while functional side chains result in additional lower-temperature degradations (215–285 °C). Side-group variation enables shifting of the glass transition temperature (Tg) between 9 and 38 °C and causes variation in hydrophobicity resulting in water contact angles ranging from 47 o to 105 o. This work presents a reliable approach to prepare sustainable polymers with diverse side chain functionalities in a short reaction time and without need for catalysts or complicated purifications.
