Biobased Epoxy Eugenol Vitrimers: Influence of Impurities of Technical Grade Monomers on the Network Characteristics

Abstract: The influence of a defined impurity on the network characteristics of vitrimers made from an epoxidized eugenol derivative and various dicarboxylic acids is reported. One major characteristic of the monomer is the fact that it is not “clean” but rather is a mixture of the mono and diepoxidized eugenol derivatives. Mixtures like this could be thought to be representative of many technical grade compounds and the current system therefore serves as a model system to evaluate the effect of epoxide mixtures on the synthesis and the properties of the final vitrimers. The vitrimer preparation is found to be not affected by the different epoxy fractions, but in terms of the properties, there is an effect on the glass transition temperature both with the type of dicarboxylic acid but also with the level of epoxy functionalities present in the system. In spite of this, the ability of the vitrimer to perform the exchange reaction is not affected and all vitrimers can be reshaped or reprocessed showing that the processing is not affected by the changes in epoxy purity.
