Abstract
In collaboration with the Biobased Materials group at the University of Maastricht, research is being conducted into the
synthesis, processing and use of biobased monomers. This involves working with renewable itaconic acid and various
diamines and thereby forming a monomer. The goal is to make the monomer three times with itaconic acid and using
different diamines. The main focus here is to reprocess the monomer. This caused problems at the University of
Maastricht.
Several monomers have been synthesized with ethylenediamine, 1,4 -butenediamine and 1,7-heptanediamine (reaction
scheme (fig. 1) according to the method of F. Ayadi et al [1] and worked up in different ways. This is done by traditional
recrystallization with different solvent compositions of water and methanol. A vapor diffusion [2] crystallization has also
been performed (fig. 2). All crystallizations are placed in the refrigerator to start crystallizatio n. Crystals have been formed
and will be analyzed with DSC and FTIR.
Keywords: Renewable, Itaconic acid, crystallisation
