The PRIC range of bio-based polyesters:
update and outlook

Intervention from Marie Reulier, Green Chemistry Project Manager at ITERG, to Polymerix 2024June 27-28, 2024, Rennes

For some ten years now, ITERG has focused part of its activities on developing a range of estolide-type macromolecules. These biosourced oligomers obtained by polycondensation reaction are grouped together under the generic name of PRIC.

Following their evaluation by industrialists in various sectors, the highly promising results confirm our strategy.

The advantage of this range lies in its adaptability in response to highly variable specifications. The range is constantly evolving, with variations in functionality, viscosity and physico-chemical properties. Estolides, with their new alcohol, acid, isocyanate and now acrylate functionalities, have been developed for applications as ingredients, pre-polymers or additives.

Thanks to constant innovation, new structures such as amphiphiles are being targeted. Finally, finding an alternative to castor oil, or at least limiting our dependence on it, is crucial; that's why ITERG is also focusing its efforts on finding new synthons of interest, made in France, to meet market expectations.
