PhD thesis abstract:
The vision of a more sustainable economy needs an environmentally friendly
alternative for the utilization of non-renewable fossil resources in the production
of materials. Particularly plastics, that are predominantly composed of oil-based
polymers, are problematic in essence. Biobased polymers could be the appropriate substitute for materials originating from fossil feedstock. For that reason,
isosorbide, a rigid diol derived from bioresources, was used as a starting material
in this study.
Linear polymethacrylates and polyethers bearing isosorbide units as pendant
groups were prepared and characterized. The influence of various substituents
and the regiochemistry of the monomers to the properties of the obtained polymers
were also studied. These biobased polymers proved to exhibit competitive properties to conventional polymeric materials.
Furthermore, the synthesis of isosorbide derivatives with elongated carbon
chain was demonstrated with the aid of hydroformylation method. By the implementation of this strategy, the derivatization of isosorbide through its secondary
hydroxyl groups can be avoided, and new building blocks with a carbon-carbon
bond elongated isosorbide structure can be utilized for polymer synthesis.
In brief, this thesis presents novel isosorbide-based compounds and polymers
that can contribute to the field of biobased materials aimed to replace plastics
from non-renewable fossil resources.
