T
he presentation will comprise industrial and academic
examples of a number of different and distinct types of
sustainable coatings entirely or partly based on renewable raw
materials. In one industrial example, alkyd resins were prepared
from new bio-based cyclic imide building blocks which were
synthesizedfromaminoacidslikelysine,glycineandphenylalanine
and fromdi- or tricarboxylic acids like succinic acid and citric acid,
respectively. These cyclic imide building blockswere incorporated
into alkyd resins by standard polycondensation chemistry and
technology. The resulting alkyd resins were evaluated as coating
resins, either by casting films from xylene or by making coatings
from water-based alkyds after emulsification of the synthesized
alkyd resins. The properties of the predominantly bio-based
coatings look promising, some even outperforming standard
commercial alkyd resins. In an academic example, the applied
raw materials were limonene mono-oxide and carbon dioxide.
A Zn-catalyzed polymerization process yielded fully renewable
polycarbonates. Solvent-based coatings as well as sustainable
powder coatings were made from these polycarbonates and
showed promising properties after curing. In another academic
example, a very promising finding is demonstrated: the possibility
to polymerize limonene dioxide with carbon dioxide, yielding a
nearly linear polycarbonate with one epoxide group per repeat
unit. This poly(limonene oxide carbonate) was decorated with
fatty acids, giving fully renewable, comb-shaped alternative
alkyd resins exhibiting remarkable properties. Finally, in yet
another academic example, the properties of coatings based on
poly(limonene carbonate) and poly(cyclohexadiene carbonate)
will be compared.
Biography
Cor Koning studied Polymer Chemistry and obtained his PhD Degree in
1987 at the University of Groningen, the Netherlands. In 1987, he joined
DSM Research in Geleen, the Netherlands. In 2000, he was appointed as
Full Professor at the TU Eindhoven and he left DSM. His research focus was
on the synthesis and evaluation of renewable step-growth polymers and he
also initiated a program on CO
2
-based polycarbonates. In 2011, he joined
DSM Coating Resins as Science Manager Polycondensates and was later
appointed as Senior Science Fellow of Polycondensation Technology. His
research interests are in the field of Polycondensates, Sustainable coatings
and Epoxide-CO
