The development of new (or improved) chemical products finds its starting point
in the definition of a chemical structure for a given application. Already at this
stage of the design process, sustainability-driven consideration can be taken into
account. In the last 20 years, a clear trend can be detected in the use of monomeric
units derived from biomass for the design of new polymeric materials. However,
???going green??? might not provide an exhaustive answer to the sustainability
issue as it could still result in the use of polluting polymeric products. The case
of polyethylene produced from ethanol (via ethylene) is paradigmatic in this
context. The combination of biomass derived synthetic strategies with relatively
novel concepts from the polymer world, such as self-healing and re-workability
(conceptually linked to the underlying concept of thermally reversible networks),
represents a viable option. In this work we will provide an overview of our current
research activities at the University of Groningen dealing with the synthesis,
processing and application of renewable and/or biobased polymeric materials.
Starting with the use of starch in bioplastics and the corresponding ???green???
processing strategy (in supercritical CO2), the concept of thermally reversible
networks will be subsequently introduced. Application of the latter to oil-based
resins (e.g. epoxy) and then to bio-based ones (e.g. vegetable-oil derivatives)
will be discussed in terms of the necessary synthetic steps and the final product
properties (including reworkability).
