Polymers derived from biomass form a fascinating field of research, offering novel materials with differentiated properties. Many of the renewable monomers can be polymd. through step-growth or, more specifically, polycondensation chem. However, several challenges are met when performing such syntheses, which may be due to a variety of reasons. For example, sugar-based monomers may be thermally less stable and/or less reactive than conventional monomers, complicating bulk polymns. in the melt. In addn., polarity differences between vegetable oil derivs. and, e.g., starch- or cellulose-based starting materials can cause compatibility issues during copolymn. reactions as well as during their subsequent application. Apart from these monomer-related challenges, new and more sustainable synthetic routes such as isocyanate-free polyurethane synthesis also require significant adaptations of the way we approach step-growth polymn. In this lecture, the mentioned aspects are discussed and possible solns. to these synthetic challenges are discussed by means of examples studied in our labs.
