Abstract

Polymers derived from biomass form a fascinating and increasingly important field of research, as such macromolecules offer differentiated material properties compared to conventional polymers from fossil feedstock. Starch is a very suitable source, which can be transferred into a range of renewable monomers to replace petrochemistry-based starting compounds in existing polymerization processes or to make completely new polymers. Recently, sources such as castor oil, cellulose and other non-edible biomass are preferred, as it is realized that the new generation of monomers from biomass should not compete with the food chain. We present a range of fully aliphatic step-growth polymers based on monomers from renewable resources, designed for (thermosetting) coating, plastic or elastomer applications. For such applications, stringent requirements exist in terms of polymer functionality, mechanical performance and thermal stability. Linear and branched, fully bio-based polyesters were successfully synthesized through melt polycondensation from succinic acid and 1,4:3,6-dianhydrohexitols in combination with a range of comonomers. These polymers were evaluated as solvent-casted films and as thermosetting powder coatings and showed very promising chemical and mechanical properties. Also by bulk polycondensation, 1,4:3,6-dianhydrohexitol-based polycarbonates were prepared. Coatings from these renewable polymers showed superior toughness, solvent resistance and gloss. In addition, biomass-derived poly(ester urethane urea) block copolymers, consisting of novel amorphous polyester blocks and well-defined urethane-urea blocks acting as physical cross-links, were prepared via an isocyanate-free route. These materials exhibit promising properties as biodegradable thermoplastic elastomers. The synthesis and characterization of these renewable polymer systems as well as a selection of their physical and mechanical properties will be presented.
