Edition of International Conference and Exhibition on

Polymer Chemistry

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

-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
